NVDA freezes when returning to android studio home after canceling the loading of a project
Steps to reproduce:
re-Run android studio after saving a project and quitting the IDE. When the progress indicator and the cancel button for the loading of the most recent project appear, press space to cancel the operation. (To return to android studio home where you can create a new project or open a project within the main layout rather than file menu)
Actual behavior:
Go to taskbar Android Studio button Android Studio pinned enter Android Studio Cancel button space NVDA freezes and keeps throwing errors every now and then
Expected behavior:
enter Android Studio Cancel button space unavailable Taskbar Welcome to Android Studio Search projects edit blank NVDA+t Welcome to Android Studio

Other questions
Does the issue still occur after restarting your computer?
It does, yes, but not all the time. It happens only every now and then
Have you tried any other versions of NVDA? If so, please report their behaviors.
No
If NVDA add-ons are disabled, is your problem still occurring?
This doesn't have to do with any add-ons according to the log
Does the issue still occur after you run the COM Registration Fixing Tool in NVDA's tools menu?
Yes
This issue is not easy to reproduce. It happens on certain conditions that I'm not yet aware of, but I'll try to reproduce it with 2022.2 as well. I just tried with add-ons disabled today, with 2022.3 Beta1, and it still happens. Also, the project that I'm testing this with isn't even that big, and I don't have the XML files opened either. There are just a bunch of kotlin(.kt) files which aren't that big.
Today I tried with NVDA version 2022.2 and the issue is still there. The error however, is a little different compared to 2022.3 Beta1. My log is below the comment text, with two errors that I got once NVDA became frozen. I have to note that sometimes, NVDA doesn't freeze instantly. It starts with some latency in speech, then if you try to make it speak the window title or navigator object, it freezes and starts throwing errors. This continues on until android studio is closed. Even switching windows doesn't unfreeze NVDA. I made sure that windows isn't frozen whatsoever using narrator; Narrator works without any issues while NVDA is frozen and all applications behave properly as expected.
As for the log for my test with NVDA2022.2, here it goes: ERROR - scriptHandler.executeScript (13:55:20.051) - MainThread (9112): error executing script: <bound method GlobalCommands.script_reportCurrentLine of <globalCommands.GlobalCommands object at 0x03759390>> with gesture 'NVDA+up arrow' Traceback (most recent call last): File "globalCommands.pyc", line 178, in script_reportCurrentLine File "documentBase.pyc", line 61, in makeTextInfo File "baseObject.pyc", line 42, in get File "baseObject.pyc", line 146, in getPropertyViaCache File "NVDAObjects\JAB_init.pyc", line 264, in _get_TextInfo File "baseObject.pyc", line 42, in get File "baseObject.pyc", line 146, in getPropertyViaCache File "NVDAObjects\JAB_init.pyc", line 261, in _get__JABAccContextInfo File "JABHandler.pyc", line 455, in getAccessibleContextInfo File "JABHandler.pyc", line 59, in _errcheck RuntimeError: Result 0

@kianoosh-shakeri are you still having this issue with NVDA 2023.1 or the last alpha version of NVDA?
You can find the last alpha version for testing purpopses here: https://www.nvaccess.org/files/nvda/snapshots/
We didn't get any updates from the initial author since more than 1 year, and during the last months NVDA's performance improved alot while several issues related to freezes have been solved. I am closing as abandoned. If the issue is still occuring, please comment and we can reopen.
