Thanks for your help.
Strange. I don’t have this problem.
I assume you tested with the latest packaged betas from Index of /downloads/beta/ or you’re running from source with a version younger than one week (i.e. with this commit)?
Maybe it’s an add-on conflict - some of my add-ons try to import other add-ons and then errors trickle down from other add-ons. To rule this out: could you disable all other add-ons and restart anki and check the add window again.
I assume you tested with the add hyperlink version I uploaded 7 hours ago for 2.1.50 - I write this because I think that this problem still persists.
Also: If you find any other compatibility problems in my other add-ons please let me know.
Also: A fix for the fastbar add-on is coming, you can also manually apply these patches from github: fixes for qt6 by ijgnd · Pull Request #14 · AnKing-VIP/Fastbar-with-nightmode-support · GitHub
