Bug / Crash Cloth abnormally twists in the CharacterCloth sample

[josemendez]

With Unity 2022.3 didn't work at all for me, the Edit didn't show the mesh.
I see, I can't use the Unity's plane xD

You need the mesh to be readable by the CPU. This is set on the mesh's import settings, but can't be adjusted for Unity's primitive meshes (plane, cube, capsule, etc).

Also, what should I reply to this? 

It's entirely up to you. Unity is offering you to automatically update some of the code to use newer APIs available in your Unity version, if you want to be on the safe side answering no is less likely to break the project.

kind regards,
