My first thought was that there might be a binary incompatibility between all the involved YaST plugins: Perl, Python, Ruby. But the crash occurring every time since 2022-06-08 15:52:08 does not support that theory: A new plugin was installed 2022-06-08 10:32:21, hours before that time, with three successful program runs of that same YaST module after that time before the crashes started.
