Grid like artefacts

Hi! my student has grid like artefacts after using the smooth and standard brushes in a lower subdivision, then going back to the higher subdivs. It progresses to vertex disorder and sharp edges from vertices jumping to far out positions.
The Ztool has multiple layers, and some polypaint. What could be the issue?
Perhaps a re-install? or making a fresh copy of the model and reconstructing the layers via projection?

Zbrush version 2021

Thanks!

I’m sorry, while I don’t know what the cause of the problem itself might be, if you are still on ZBrush 2021, it would be a good idea to upgrade to the latest version, 2022.0.5, not only for the new features it brings, but in case this is a bug that has been fixed in later updates. It’s a free upgrade, just download it from your My Licenses page.

Not a bad idea, but not currently applicable. we have to keep uniformity of software for this semester.

Ok, correction, the version in question is 2022.5 so wer’e pretty up to date. if anyone had something similar happen please post, would be nice to get a clue to why this happens
