From ParaView 5.9.0-RC2 going back to ParaView 5.8.1 I can make it segfault after reading in a fairly big vtkmultiblock object (900MB) that consists of ~5000 DataSets vtp. File -> Open -> select vtm and then hit apply. Do random things in the VTK render window like zoom in / out / right click on blocks / left mouse click on parts and it will eventually crash. I can get it to crash on Pick or PickBlock. Here is the seg from PickBlock
Loguru caught a signal: SIGSEGV

I’ll see if I can attempt to get this to happen in other formats.
Thanks,
