@salfum did you try compiling expert using 1.16.0? From your original post it looks like you compiled at a higher version than your project version?

@salfum can you provide the logs in .expert/project.log? The error you're seeing is benign(as in, it's not what's causing the crash) so I presume the project node is crashing and your editor is terminating the LSP process
