Paraview 5.9 stopped working

Nope. Sorry. That didn’t work, but I think of similar cause, since installed Paraview (version 5.9.0-1
, from aur: Arch User Repository) & packaged binary behaves in the same way…

Here I’m posting the error from the downloaded version (ParaView-5.9.0-MPI-Linux-Python3.8-64bit/bin/Paraview). This might give some hint to you guys, but not in my forte:

Loguru caught a signal: SIGABRT
