I have tested the AppImage
When i tried to launch atlas i got this Message
in the logs I found this
DllLoader: dlopen(libAtlasUI.so) failed: libAtlasUI.so: cannot open shared object file: No such file or directory; dlopen(libAtlasUI_dbg.so) failed: libAtlasUI_dbg.so: cannot open shared object file: No such file or directory;
After a discord discussion there are some other options possible, such as tweaking build restrictions. In this case though, it would not be possible to change the passability class number restrictions without touching C++ code.
