Looks like a duplicate of: https://developer.blender.org/T72175

No crash here.

Note: for those kinds of cylinder-like objects [lots os faces connecting to ngons], you are much better off restricting this to edge bevel weights [you end up with better topology...]
But that just on the side...

Please try with File → Defaults → Load Factory Settings to see if you still can reproduce this issue.

Not sure if it's the same since in the T72175 is related to the Subdiv modifier and this is about the Bevel modifier... but who knows, maybe they are related?
Thanks for checking that in another version it doesn't crash.

Ah, OK, was testing with rB6ba09f8515bd, indeed rB722b8e469282 crashes...
Anyways, this is resolved now, so will merge this report with T72175: Crash When Drawing Large Meshes

I follow your suggestion to Load Factory Settings and I still get the crash if the Segments are greater than 2.
