It’s still not clear that this is a problem Anki can solve for you. It’s happening across multiple versions, and Qt5 and Qt6. Anki’s video drivers don’t make a difference, and it’s unaffected by add-ons.
You’re using Windows 11, which seems to be the culprit, but this isn’t a widespread issue, so it seems like it’s something in your particular system. I don’t know if you followed through with all of the other suggestions about Windows I gave you a couple weeks ago on your original reddit post, but I would advise that.
It looks like you haven’t tried running Anki from a terminal window yet – that might give some insight into exactly what is happening when Anki freezes up. Startup Issues - Anki Manual
The only other Anki thing that might overcome interference from the OS is to do a complete uninstall of Anki (just the app, none of your data will be touched), including deleting your Anki program directory – the default location is %LocalAppData%\Programs\Anki\. If there is anything that the OS or another app is controlling, a fresh install might allow Anki to assert itself.
