My Dad has this issue as well, it's related to MS OneDrive trying to backup/sync to the OneDrive cloud. I believe the solution is to create a new folder for iCloud Photos outside of the OneDrive folder. Then remove the iCloud photo from as one of the ones to be backed up by One Drive. Then you can move the iCloud photo to the newly created location outside of the OneDrive folder on your PC. Next you go into the online version of One Drive and delete the iCloud Photo from there. So at this point, One Drive should no longer have a copy of the iCloud Photo folder, and it should no long be backing it up. Your iCloud Photo file should be mapped to the iCloud Photo folder this is now outside of the One Drive folder.
Now to remove the ghost iCloud photos folders in the Quick Access, follow the solution provided by That Laggy Guy' second post on the link below:

I believe following all of these steps should prevent multiple iCloud Photos folder from reappearing.
