Hmm, I can't reproduce this, on either a debug build or a release build. What I did:

Extract the blend file
Open the file
Click the monitor icon in the modifier header (no crash)
Enter edit mode (no crash)
Add a camera and render the scene (no crash)

That's a bit peculiar. Does this this happen consistently for you? Also with the latest daily build?

@HooglyBoogly , crash sometimes does not occur on first try.

Try toggling (monitor icon) multiple times if it does not crash on first attempt.

I toggled the monitor off and on for a while on debug and release builds didn't get a crash. However, I have found that the normals look completely wrong compared to 2.93, so clearly there's something going wrong here. Maybe the two issues are related.

It happens consistently for me, I cant even open the file without crashing if the modifier is already enabled on the object. Here is the crash log from it.
