I’m getting this message, and I’ve seen a similar message on this forum before, and it was suggested to download a more current version of Anki. This fixed the problem for that user, but I have tried downloading both the Qt5 and Qt6 version for my Mac (not M1/M2 chip).  
Any help would be appreciated!

Try going through these steps, especially if Anki was working before: [When problems occur - Frequently Asked Questions](https://faqs.ankiweb.net/when-problems-occur.html)
