This seems to happen consistently if the projects are stored on an EXFAT partition. Consider using another filesystem, such as NTFS if you still need projects accessible under both Windows and Linux.
### Built avatar appears non-stereoscopic to me and everyone else
Ensure the filesystem your project is on has not been mounted with `noexec`.
With `noexec`, the shader compilation plugin from VRCSDK will fail with a warning:
> Plugins: Couldn't open /run/media/blahblahblah/MyProject/Packages/com.vrchat.base/Editor/VRCSDK/ShaderCompilerPlugin/Plugins/Linux/x86_64/libvrc_shader_compiler_plugin.so, error: [...]: failed to map segment from shared object

The `noexec` mount option may also contribute to other issues such as being unable to run any binaries from inside the project, such as avatar patchers.
