The Linux version doesn't seem to work! Got this error:
ERROR: Pack created with a newer version of the engine: 3.5.
at: try_open_pack (core/io/file_access_pack.cpp:180)
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).
