After updating to 26.09.3 on windows 10, when I open Anki I see the top toolbars but below them the screen is blank. When I open Anki with the shift key pressed down, it reverts to normal. I have disabled all the add-ons but the problem persists: only by starting with shift can I see the main screen. I have tried the other video drivers which did not help. This means I can use Anki but no add-ons. Is there something else I should try?
Switching the video driver should help:
Can you run Anki from the console as described in the link and post the output before doing that?
