@anon-qg My first thought would have been in regards to the Anki version, but you said you tried them. I think .49 is the one that is considered compatible, but you probably already tried it. Often times developer attention can be gotten on the Discord server quickly, so if you're still having trouble, I'd go there next. They seem to be quite interested in resolving critical errors such as the one you are running into since it might be a serious bug.
