I have the same problem on Linux Mint 18.3 (Ubuntu derivitive). I could
access files and folders except for the folder containing a whole lot of
images. Error message was:
The folder contents could not be displayed.
Sorry, could not display all the contents of "Wallpaper" : libmtp error: could
not get object handles.
I tried restarting the computer, and the phone independently - neither
resolved the issue. After researching this issue, several people
suggested that the number of files (in the folder) may be an issue.
This work-around resolved the issue for me: On my phone, I created a new
folder at the same level as the problem folder, and moved 1 file from
the problem folder to the new folder. I could then access the problem
folder from my Linux machine. I copied some more files into the folder,
and then moved the relocated file back into the previously problematic
folder and could still access the folder. I then removed the newly
created (and now empty) folder.
Ok. Some more information that may help resolve the problem:
There were 1788 files in the folder when I encountered the issue.
There were 1787 files in it after I moved 1 file and could access the folder.
There were 1816 files in the folder when I'd finished copying files (and it was
still accessible).
The folder containing the files is a sub folder of another user created folder
on the phone.

Title:
libmtp error could not get object handles
Status in libmtp package in Ubuntu:
Confirmed
Bug description:
When connecting my android galaxy s7 phone via usb, I am unable to
access my Music folder, which contains 380 subfolders. The file
manager is inactive for a long time, and finally displays the error:
Sorry, could not display all the contents of "Music": libmtp error:
could not get object handles.
Adding one more subfolder on the android side seems to work around the
issue, so the issue is related to the number of items.
Given this, my issue appears to be a specific example of the issue described
in the link below.
