I couldn't get the linux build to work, I am on Manjaro (archlinux). I got this error message when I tried to run the .x86_64 (I don't have any .pck file in the folder after running the exe):
Error: Couldn't load project data at path ".". Is the .pck file missing?
If you've renamed the executable, the associated .pck file should also be renamed to match the executable's name (without the extension).
