That is what I tried first:
Just realized that I could start it from the command line and I see:

Failed to compile shader:
Source was:

...
Could be that that is because I did change a SDDM config file but not that nice to crash instead of reporting an error indicating parsing which file triggered the problem.
Other functionality of the System Settings work as expected.
