Anki opens with only menu bar visible, rest of the window is blank

I just did the math and realized you’re using the beta version. You should –

  1. Make sure this is still happening using the most recent beta release.
  2. Read the beta thread and make sure this isn’t already reported – Anki 24.10 Beta .
  3. Report it in the beta thread.

Then, as an alternative to get you running again, you can go to File > Switch Profile > Downgrade & Quit – and then install the most recent released version of 24.06.
