I've isolated a problem on my Debian server.
Operating System: Debian GNU/Linux 11 (bullseye)
Kernel: Linux 5.10.0-17-amd64
Architecture: x86-64

Mods: (latest)

Thx

Can you post the entire crash-report? It's quite hard to figure out the issue that way.

I will close this issue for now. If it still persists post the entire crash-report here and I will reopen the issue.
