Cannot add tags or open Quick Edit

Block Editor will also not open.

The Classic Editor does kind of work – content is saved but it will not let me add tags and shows an error page when save (although the main content is saved).

If try to open Quick Edit, I see the following error in the browser console :

load-scripts.php?c=0&load%5Bchunk_0%5D=jquery-core,jquery-migrate,utils&ver=6.1.1:5

If try to add tags, I see this :
