Short description of error
Press the space bar, the animation starts and Blender closes. The console says : EXCEPTION_ACCESS_VIOLATION
I also test the file with an independent portable version of Blender, but the crash still occurs.

Exact steps for others to reproduce the error
Press space bar to play the animation and wait the frame 48.

Hi @Rudy-MICHAU , I'm unable to replicate the crash in either 3.6 or 4.0. No matter if it's frame 48 or played indefinitely. Also the scene doesn't seem to have anything animated. Could you try the steps here and give us the crash log? Thanks!

Could you try the steps [here](https://docs.blender.org/manual/en/3.6/troubleshooting/crash.html#windows) and give us the crash log? Thanks!

My bad, excuse me, I think I joined the file before animation addition !
The file and log here.
The boolean object modifiers are animated.

I do get a somewhat garbled result in frame 49, but still unable to replicate the crash despite repeated playing (3.6 or 4.0), maybe it's due to co-planner meshes being booleaned. @Rudy-MICHAU Could you try moving the bevel object slightly from its initial position and see if it works?

Crashed at somewhere inside bevel_build_edge_polygons().

Nice ! No crash if I move up it a little bit. 👍
So Blender bugs because to close faces.

Can replicate actually.
Looks like a regression between 3.4 - 3.5
Raising the priority.

Also got Invalid clnors in this fan! error in console which is related to custom normal (I guess).
Clearing custom normal from Cube.copy.001 object still triggers the crash.

Looked at this a bit today. So far my guess is that the fast boolean code can generate an invalid mesh, which triggers an assert in the bevel modifier. I'll look at it more tomorrow.

Not a regression actually. If I clear modifier visibility keyframe then enable modifier at first frame, it would trigger the crash.
