Short description of error
I have made simple Geo Nodes setup - generate bunch of Curves instances, randomly on surface of mesh with Realize Instances. Lets say we duplicate this modifier second time (on same mesh object) - and we Join Geometry of new mod generated curves with previous modifier generated curves. Blender will crash.

Exact steps for others to reproduce the error

  1. Join Output of Separate Components[Curve] socket to JoinGeometry[Geometry] socket as shown in image below with red line. Blender 3.0 will crash.

Additional Info:
Removing output attributes from previous modifier (Normal, Tangent, Factor, Random) - helps to get rid of the crash.
