Mouse movement with "Play audio coordinates when mouse moves" enabled fails with exception

[Danstiv]

Steps to reproduce:

1. Go to nvda mouse settings.
2. Enable "Play audio coordinates when mouse moves" setting.
3. Enable "Brightness controls audio coordinates volume".
4. Try to move the mouse physicly or using nvda mouse movement gestures.

Actual behavior:

Exception raised, and no beep was played.

Expected behavior:

Nvda should not raise exception, and mouse audio indication should be played.

Does the issue still occur after restarting your computer?

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

Some old snapshot from 05.08.2025 works correctly.

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?

Hi!

I tried to reproduce this issue on my setup, but everything works as expected.

Audio coordinates are played when moving the mouse and no exception is raised.

Actually point brightness detection fails, so exception is raised when Play audio coordinates when mouse moves enabled, and Brightness controls audio coordinates volume is also enabled.
I just found this out, also updated STR.
