Runtime error (macOS)

[Christoph Schmitz]

Since a few days I get the following error message when starting a newly compiled version of LyX:

Unable to determine the system directory having searched
/Users/chris/Desktop/LyX.app/Contents/Resources/
Use the '-sysdir' command line parameter or set the environment variable
LYX_DIR_24x to the Lyx system directory containing the file "chkconfig.Itx'.

The contents of the folder ./LyX.app/Contents/Resources/ is completely different when compared with the contents of the last working version. If you manually copy the contents to the newly compiled version, the program starts up again.

I have the same problem on two different computers running macOS: an Intel machine and an M1 machine.
