Hi @joejetta I am sorry if you have already done some searches here on this new forum and maybe the Old Zorin Forum archive
If not, there are a number of threads on here that discuss login loop problems, including this: Resolving Login Loop issues ... should they occur!
Note the first mention in that post by @swarfendor437 refers to corrupt files.
What version and flavour of ZorinOS are you running, e.g. Z15.3 Core or Lite, or maybe Z16Beta?
