Need some help with AC, CM and SRP. Crash only on official server

As per title, I'm trying to join the official server of Shutoko Revival Project, but it crashes AC every time.

If I play single player or join a different server racing on SRP, AC doesn't crash.

Tried latest untested CSP (0.2.2) and 0.1.79, on latest I get a generic crash message, on 1.79 I get an error with CSP.

I tried reinstalling the track and the cars, no change.

I also have a crashlog but I can only read about missing cars textures and such, which is strange since it doesn't happen if I play single. If there was an issue with those textures I woulnd't be able to play single either, would I?

This is on Linux.

Thanks in advance!

I can't access their Discord server since it's gated behind a phone verification, that's why I'm trying here
