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.

I tried source at release-2024.1beta2 tag, that not include this commit from #15960, that introduced the issue.

I'll provide a fix in minutes; but considering the above commit, I'll try to make a PR on beta branch.

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?

Not relevant.
