Hello there,
I just began having this issue this morning. I tried changing a card’s deck, and the browser window froze on me. Even though I could still navigate the main window, the browser window remained frozen. I couldn’t unfreeze Anki without force-closing the application. I tried to check the add-ons as well, but when I tried to open the add-ons window, the same freezing issue happened, but this time with the main window. I restarted the app again, and I tried to reproduce the freezing with opening other dialog windows, but wasn’t able to reproduce it with anything other than the add-ons and change deck windows. I started Anki without add-ons, but the same thing happened with add-ons disabled. I went to a different profile to see if the freezing would happen there, and it did not. I checked the database on the original profile, but that had no effect on the freezing. I updated my Anki version to 2.1.35, and made sure all of the add-ons were up to date using the test profile, but the main profile still froze upon trying to change card decks or opening the add-on window (even though all of the add-ons seemed to be working fine). Restarting my computer did not help. The problem seems to be happening only with my original profile, and does not seem to be add-on related. I logged out of AMBOSS as well, just to be sure, and the issue still persisted. Any thoughts?
Thank you all in advance!
