Unfortunately, we don’t support the development of VRChat content on any platform except Windows! :S

The first stack seems to point to some issues with reflection, which is probably the main culprit. The second is a null ref which is probably caused by the first.

Reflection is a pretty fragile process and I would expect it to break in an unknown or unsupported environment like Linux Mint.

Can you copy the project over to a Windows OS (perhaps a VM?) and try in there?

i can try, thanks for the help :3

One of the known solutions is in this tweet (written in Japanese).

You can try it if you like.
