Have you re-started revit, and is it still happening?
I had something similar, a Addin was causing this under Windows 11 (under Win 10, it didn't do that with same Revit + update + addin version) It also cause the UIView panels to pop-out and soon after the model would crash.
It seems like Revit was handling a single click as double click, but internally revit didn't follow that so it became unstable. After uninstalling that addin I never experienced it again. Not necessarily the addin fault but combi Addin + Win 11 + maybe some win drivers for mouse (tried others)
