Updated to Big Sur and every time I open preferences Devonthink 3.6 server crashes. I have seen others having the same issue.
Welcome @adempe
This will be addressed in the next maintenance release. Stay tuned. Thanks for your patience and understanding.
Feel free to tag on to a pertinent thread, rather than opening a new one when your subject has already been covered (multiple times) in the forum. That helps keep things tidy and aids others in finding helpful posts too.
The (rather limited) options for solving this problem have been posted in those other threads (eg here or here)
