Issue 45641: Error In opening a file through tkinter on macOS Monterey

there is an error that is occurring in opening a file or program & after that python is started hanging & not even quitting.
And also the file which is open by python is not even saving or executing.

You need to give us some steps to reproduce this error, or we cannot even begin to try to fix it.

What are the minimum steps needed to reproduce the error?

Please read:

https://stackoverflow.com/help/minimal-reproducible-example

http://www.sscce.org/

For that,
First, open IDlE
Then click file & then click on Open 
After that it's showing the error THE OPEN FILE OPERATION FAILED. 
Note: I didn't open any file

This is the File which is opening every time and not even saving it.

Are you using macOS 12 (Monterey)?

I get an error as well using that version of the OS (see open-error). The error happens within a second or two after opening the open dialog, without interacting with the dialog in any way. This is on an M1 laptop running macOS 12.0.1.

This is likely the same issue as described in #44828. In particular, I get the same error message when I run the reproducer script in that issue. 

I'm adding the Tkinter component as well because this is likely a problem

Yes,
 I also have a MacBook Air M1 & I recently updated it to macOS 12.0.1. 
How to get rid of this error ??

See issue #45642

Ya, I saw it, same thing is happening with me.
But now what?
what is the solution?

Same issue for me on Mac OS 12.0.1 hoping for a quick solution to this

> This is likely the same issue as described in #44828

I agree; Ned and Marc are working on it. I doubt the patch will be ready for 3.9.8, but it'll probably be in 3.9.9 and 3.10.1.

What happened?
when is the new version is coming for tackling this problem?

The patch was merged in #44828 and backported to 3.8, 3.9 and 3.10 (i.e. it will be in 3.9.8).

See msg405488: an updated macOS installer for 3.10.0 is now available as the default download from python.org.

Ya, it's resolved but, The saving prompt is not closing after saving the file.

Thanks for the report. We'll look into it on Issue44828.

An update: we believe that the problem with the Save dialog window not closing has been fixed in a revised updated macOS installer for 3.10.0 which is now available as the default download from python.org. See Issue44828 for more details.
