Please narrow down until you know for sure which add-on is causing the problem to properly report to the add-on dev

2. Check add-ons
Please close Anki, then open it in safe mode by holding down the Shift key while starting Anki. Keep holding Shift down until the on-screen message informs you that Anki has started in safe mode.

If the problem goes away, that indicates an add-on is causing the problem. Remove any add-ons you don’t need, and disable half of the others. If the problem continues, try the other half. Repeat the process until you’ve figured out which add-on is causing the problem. Then please report the issue to the add-on author, using the Copy Debug Info button, and pasting that into the report.

The add-on Ruzu Pop-ups may be the cause, try to disable it.
