This issue is happening for me in with my installation of python 3.10 running 
the release version of mac os monterey 12.0.1 running on an intel mac, I 
noticed this behavior trying to open or save files in IDLE.

[Guy DeStefano]

Guy DeStefano  added the comment:

Please help me.  Am new to Python, and don't know enough to post here, but I 
will try.  Have written a couple of programs that use tkinter, especially 
tkinter.filedialog.askopenfilenames, and as everyone else mine has quit working 
since Monterey. I have a macOS Monterey version beta( 21A5543b ).  Am 
using Python3 v3.10.0.  Have tried using v3.11.0a1, but could not even compile, 
says that import ( PIL ) does not exist.  Put back v 3.10.0 and am back to no 
filedialog.  Is Apple attempting to do away with the file API.  Just asking. 
Thank you.

Marc Culler  added the comment:

Hi Ronald,
There is no calendar scheduling for Tk releases.  Don Porter decides when they 
happen.  But I think we are due for another one soonish.  In case it doesn't 
happen before the next Python release I will attach the patch file for commit 
a32262e9.  (Note that this is subject to change - I still need to test on 
10.14.) I believe that this patch is completely self-contained and can be 
applied to the 8.6.11 release.

(Hint: Tk uses fossil as its SCM system.  On a fossil timeline, clicking any 
two nodes generates their diff.  The Tk timeline is at 
https://core.tcl-lang.org/tk/timeline)

Marc, thanks for the update.

Will there be a Tcl/Tk release soonish that includes this fix? 

Alternatively, is there patch that we can apply to the latest release when 
building the copy of Tk included with the installers?

[issue44828] Using tkinter.filedialog crashes on macOS Python 3.9.6

[Marc Culler]

Marc Culler  added the comment:

I was able to fix this problem for Tk on Monterey beta [21A5543b].
The fix has been committed to the tip of the core-8-6-branch in the
Tk fossil repository.

Here is a synopsis.  Tk used to open the file dialog by calling
[NSApp runModalForWindow:panel].  Starting with the release of 10.14
this call would produce a warning message on stderr saying that
[NSOpenPanel runModal] should be used instead.  But on systems older
than 10.14, the runModal method would fail because the completion handler
would not get called.  Now, with 12.0 (at least in the beta) calling
[NSOpenPanel runModal] produces an error dialog saying "The open file
operation failed to connect to the open and save panel service" and
this would be accompanied by a traceback printed on stderr for an
assertion error.  (It was not a "crash" but the file selection would
fail.)  However, it turns out that calling [NSApp runModalForWindow:panel]
no longer produces the warning in 12.0, and it works correctly.

So my workaround was to add conditional code that only calls the runModal
method on 10.14 and 10.15 and calls runModalForWindow on other versions
of macOS.  I tested on 10.15 and it works there as well.

Needless to say, none of these changes are documented by Apple.

Unfortunately, I am still seeing this failure in Monterey beta 9.  However, we 
are no longer alone.  Here is a report of the same issue in Android Studio:

https://stackoverflow.com/questions/69068842/android-studio-open-file-operation-failed-the-open-file-operation-failed-to-co

This is reportedly fixed in the Adroid Studio beta, so maybe someone will be 
able to figure out what Google did to workaround the problem.

Is there any plan for a fix or is the plan to wait for Monterey to release?

Fahim Faisal  added the comment:

Can also confirm this issue, tested on M1 and Intel Mac and both has the same 
error when using Monterey 12.0 Beta 21A5506j. 

On the same computer, using Big Sur, saves the file successfully and no error 
present. Seems like a Monterey issue, not dependent on specific hardware. 
(Intel/M1)

Tested on fresh Python 3.9.6 (tk version 8.6) Installation on Big Sur and 
Monterey Beta (Build 21A5506j) on a M1 Macbook Pro and Early 2015 13" Macbook 
Pro.

Mark Lierley  added the comment:

I am also experiencing this issue.

I have an M1 Macbook Air running MaOS Monterey Version 12.0 Beta (21A5304g) 
with a fresh install of Python 3.9.6. 

When attempting to save or open anything from either the editor or console 
window I get the following error message "The Save file operation failed. The 
save file operation failed to connect to the open and save panel service.”

I have granted the IDEL full drive access which hasn't resolved the issue. The 
dialog prevents any savings from occurring making the IDEL useless. 

I have submitted this issue through Apple's Feedback tool as well.

[Marc Culler]

Marc Culler  added the comment:

I built Tcl and Tk 8.6 on Monterey beta (21A5294g) and I see this
traceback in the Wish file dialog demo.  Note that this is *not* an
error.  The file dialog works fine.  This is a non-fatal
NSInternalInconsistencyException which prints a traceback to stderr.
It occurs within a call to [NSSavePanel runModal] which is entirely
Apple code.  The runModal method is not deprecated.  Most likely, when
Apple releases Monterey the assert command will have been removed,
possibly replaced by a call to NSLog which writes information into a
log file rather than print it to stderr.  (NSLog itself prints to
stderr when debugging is enabled.)  Of course macOS apps run without
stderr, so you will only see this traceback when running a python
program from the terminal.  (Any linux user who runs linux apps from
the terminal is used to seeing lots of stderr messages in stderr.  Try
running okular from a terminal sometime.  So we shouldn't complain too
much.)

Anyway, this looks harmless and the messages will almost surely go
away in the production version.  However, there are several new
deprecations related to specifying preferred file types in a file
dialog which I will address in Tk before Monterey is released.

Beta releases are betas, even for macOS.

As far as I know, Homebrew builds its own Python and Tk.

Thanks. I think the next step would be to try to reproduce just using Tcl and 
Tk as this most likely is an issue in Tk rather than Python.  It's also quite 
possible that the underlying problem will be fixed in a future Monterey beta. 
Alas, I don't have time to look further into this in the immediate future.  
Perhaps someone can follow up directly with the Tk folks.

I used brew.sh to install Python, which I think uses the universal installer 
(although I can’t check, reinstalling macOS after hours of failing to downgrade 
back to Big Sur). I can’t remember the exact error, but it seemed to be from 
Apple’s end since it complained about not having access to the save/open dialog 
box. After I reinstall macOS, if you need further testing, i’m open to trying.
