NullReferenceException on right-clicking administration building

[dbtrnl]

My KSP suddenly got very slow and crashed, right after i right-clicked the administration building.
Other times, the same error popped in the console, but the game didn't crash. Now apparently the game entered a loop and crashed.

I'm using 1.9.1

I've seen this reported elsewhere, but I haven't been able to reproduce it. Could you provide the mod list (or just a KSP.log file would probably be better)?

Principia is also installed (Gallai release, i believe). Also, i was using Ubuntu 20.04.
The lagginess also happened in apparently random moments when flying rockets or airplanes, so i suspect other mods.

Actually i already gave up on trying to play KSP on Linux, cause i don't see any way to debug the random lagginess (i would appreciate if you know any tools besides the game debug console).
Almost every time i have to REISUB (can't even xkill).
I suspect some bizarre memory leak/lack of code optimization for Linux, but i don't know where to start. This Exception was the only big error shown (besides the many warnings). I could keep digging though.

I've been playing with a similar modlist on Win10 and encountered no problems with Strategia or KSP in general (despite the 15 minutes load times on my old computer).

My KSP.log. There were actually tons of errors, so i'm sorry if any of them are known.
I'll check later if those tons of errors also appear on Win10.
