(bug) Unable to add cards due to MPVTimeoutError

When trying to add a card or review certain cards I receive the error posted below. I tried the “Check Database” tool as instructed but that that did not fix the issue. I also restarted Anki and my computer and no help.

Maybe, at first try to download the latest mpv version from https://sourceforge.net/projects/mpv-player-windows/files/64bit/ and copy everything to C:\Program Files\Anki to replace mpv.exe. Then restart Anki, open the Debug Console, copy-paste these lines and press Ctrl+Return, just to confirm that mpv is working and it’s the latest version.

from aqt.sound import mpvManager
print(mpvManager.get_property("mpv-version"))
