I can confirm.
In a debug build, editing the material can still lead to a crash:

Confirming this as well but I would also say that geometry generated inside Geometry Nodes needs to have the material assigned to the object data not the mesh data:

Doing this fixes the issue.

@mano-wii Does this crash still exist, I couldn't reproduce it. Can you give some more precise steps to reproduce the crash?

Besides that @Erindale provided the correct workaround that is necessary currently.

Anyway, I tested it here and it seems that it doesn't happen anymore :)
