Steps to reproduce:

1. Install NVDA-Alpha-28685
2. Install "Instant Translate" or "UnigramPlus" add-on.
3. Restart NVDA

Actual behavior:

The add-on failed to load because the settings panel failed to initialize.
Try typing from gui import SettingsPanel in the NVDA Python console and execute it.

Traceback (most recent call last):
  File "<console>", line 1, in <module>
ImportError: cannot import name 'SettingsPanel' from 'gui' (C:\Program Files (x86)\NVDA\library.zip\gui\__init__.pyc)

Expected behavior:

Add-on compatibility should not be broken

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.

alpha-28675 can't reproduce this, I suspect it's a regression of #15121.

No

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

Yes
