Other questions

Does the issue still occur after restarting your computer?

Yes

Have you tried any other versions of NVDA? If so, please report their behaviors.

Can't reproduce this with 2022.2.2, so this may be a regression.

If NVDA add-ons are disabled, is your problem still occurring?

Yes

Does the issue still occur after you run the COM Registration Fixing Tool in NVDA's tools menu?

Yes

It would be good to prevent this error from occurring or to capture it as a logged warning, however this issue does not affect the user.

NVDA keeps playing error sound when lots of errors are thrown, speech lags. It's a regression that also affects users in a way.

[seanbudd]

@cary-rowen does this affect behaviour for a released version of NVDA, which does not make error sounds?

[cary-rowen]

The issue cannot be reproduced in 2022.2.3, no logs are logged at all. 2022.3Beta5 can't off the error sound to test, so I don't know what effect he has on the release version.

[cary-rowen]

Update: test.bat.txt

1. Download the above Test.bat.txt.
2. Be sure to change the file name to t.bat.
3. Execute the script.
4. Quickly press Alt+Space,C to close the cmd window.

Actual performance

NVDA throws a lot of errors. This only occurs when accessing the Windows Console using UIA. @seanbudd @codeofdusk

[codeofdusk]

What is the "API level" of your console (in <Kbd>Nvda+F1.)?

[cary-rowen]

For me it was "API level: 2 (FORMATTED)" I manually replaced "conhost.exe" with the new version. But even the old version has the same problem.

[cary-rowen]

What do you think about this? @codeofdusk

[cary-rowen]

This issue seems to have been resolved in latest alpha version. I'll watch it.

[Adriani90]

@cary-rowen can this be closed in this case?

[cary-rowen]

@Adriani90 Sorry my previous comment was wrong, I updated the steps to reproduce the issue and it is still stable to reproduce.

[cary-rowen]

I think this issue has caused some confusion, it is not conducive to the problem being solved, so I will close this issue and create a new issue.
