Reinstall All Parts of a Julia Project

I am attempting to run Julia on a HPCC. The most up to date version they have is v.1.10.

I have somehow broken a project, so that whenever I try to load Julia v.1.10, not limited to this specific project I get an error

ERROR: KeyError: key "TypeParameterAccessors" not found
related to a specific package I had installed (ITensor).

I have tried deleting the .julia folder and every possible directory I have access to, in order to reset the project, but to no avail. How can I completely reset things so that I can start from scratch?
