I tried the debugging, but
then it starts spaminh
mpv timed out, restarting
without stoping
I get problems with mpv when i put the pc on sleep/hibernate, maybe restarting could help
Could be an add-on problem → try opening anki in safe mode (holding shift while opening anki) and search for the add-on that could be disrupting it (had this problem with pomo)
Maybe reinstalling Anki on the latest stable version could help
If you remove mpv.exe from \program files\anki, what happens?
