System Information
Operating system: Ubuntu 22.04.1
Graphics card: GeForce RTX 2080

Blender Version
Broken: 3.2.2
Worked: Unknown

Short description of error

Uh....
statistics.blend
Exact steps for others to reproduce the error

This appears to be due to some combination of Rigid Body, Cloth, and Collision settings on two or more objects, and the order of enabling them on the objects. Normally I just get it to exclude the component counts from one object, but both of them is quite impressive....

Thanks for the report.
I'm able to confirm this in 3.3 but not in 3.4. I guess this has been fixed by f12f7800c2
Can you check in latest 3.4 build?: https://builder.blender.org/download/daily

Confirm this isn't an issue in 3.4

Also, dependency cycle is detected in your file.

Yeah, well, I can't do anything about that:

I'm going to have multiple cloth objects that need to interact with each other. Adding a Collision modifier to multiple Cloth objects creates a dependency cycle.
I would like to have the cloth objects affect rigid bodies (it's finicky and sometimes gets bizarre results, though). Adding a passive Rigid Body to the Cloth objects can create a dependency cycle (maybe in conjunction with some of the other options?).

Some of the dependency cycles seem to occur based on previously cached/used data or something. If I delete all collision/physics info out of one of my files, save/reload, then enable rigid bodies and collisions on two objects, I get a dependency cycle, but I don't if I create a new file and create the rigid bodies/collision modifiers there.
