so i find something interesting after rebaking

in the frame 199 there is no particles well there is no volume
maybe this is related to the problem
BTW there is another crash but I still don't know how to reproduce it it seems it happens randomly

so this is a bug that happened after the bug above happened automatically
blender collision objects missing.mp4

when this bug happened the bug above stops there is no crush and frame 199 will be baked normally

I was baking this file and crash happened, but this seems to be in mantaflow. Not sure if this could be avoided by Blender.

Similar report already exists- #87975 (Mantaflow simulation stops and crashes at the end of the bake (or when closing blender): The CG solver diverged, residual norm > 1e30, stopping.)

Sounds similar, so will merge.
