[issue38974] using tkinter.filedialog.askopenfilename() freezes python 3.8

[Colin Caprani]

Colin Caprani  added the comment:

In case it helps, I have the same problem. Running python 3.8.8 on Windows 10, 
and any MWE doesn't work, e.g.:

from tkinter import filedialog
from tkinter import *

root = Tk()
root.filename =  filedialog.askopenfilename(initialdir = "/",title = "Select 
file",filetypes = (("jpeg files","*.jpg"),("all files","*.*")))
print (root.filename)

I just get the spinning circle and unresponsive dialog. I have quite a few 
shell integrations so uninstalling them is not ideal.

Terry J. Reedy  added the comment:

filedialog.askopenfilename returns 'Open(**options).show()'.  IDLE's File => 
Open (^O) calls Open and show directly.  It continues to run on all versions on 
my machine (and presumably those of numerous others).  I have TortoiseGit now 
and only recently removed TortoiseHG, so those two seem well-enough behaved.  
This is almost certainly not a cpython issue, but it would be good to know 
where the problem lies.

Temporarily uninstalling your Dropbox client is the easiest way.

Steve Dower  added the comment:

Potentially. I don't have it installed, so I can't test, but I know in the past 
it added a shell extension that would display overlays over files it controlled.

That shell extension will be loaded into most system file picker dialogs, and 
at various points has executed Python code. I doubt they're on 3.8, but it's 
possible that there is some kind of conflict.

Can you try uninstalling or disabling its shell integration?

I have dropbox installed, would that be what's causing the problem?

Processor type is far less likely than a shell extension.

Do you have anything like DropBox/Tortoise???/etc. installed?

No, it is an issue with Windows. I think it might only be a problem with my 
computer though, maybe the fact that I have an AMD processor might have 
something to do with the problem?

What is your OS? Is it macOS specific issue?
