If you have a df-ai-debug.log file, drag or paste the file into this issue.
How do i enable generation of df-ai-debug.log ?

If there's no df-ai-debug.log, that means the crash wasn't something df-ai detected before it happened. This could be a misaligned structure or some other problem with how df-ai is accessing that screen.
