I am using plasmo version 2.0.8 for 1.20.2

The game crashes seemingly at random after around a minute of running. It has to be due to Plasmo, because it happens only when this mod is present. The crash doesn't generate a report, but here's the latest.log file:

I can't really help you with this amount of information.

I can only suggest to try 2.1.0-SNAPSHOT, which uses different natives, so it may help.
