Mac misbehaving after latest Update

So I updated Mac OS to 15.3 a couple of days ago and since then there's all sorts of stuff is happening; \- frequent app crashes and unresponsive apps (all over the place - finder, notion, sketch, music and on and on) \- photoshop is telling me my GPU is incompatible all of the sudden? (M1 Max) \- frequent slowdowns Anyone else having a similar issue? or have an idea how to fix this without completely nuking the system? Thanks a bunch
