The desktop app isn't booting up automatically on Mac OS, and there's two Dropbox folders

i have three mac computers running same software and configurations - all on latest tahoe - all have dropbox on them and until recently all logged dropbox in automatically on restart (nothing accessibility and privacy have correct settings and disk access) - i also have dropbox files on the computers and not just iCloud - multiple times have uninstalled and reinstalled dropbox to try and fix - recently i found the advanced reinstall pages on dropbox with some terminal instructions - when i went to reinstall there was for first time toggle to opt out of File Provider which i did not click - now i have two dropbox file folders - one under user name (with the complete files on computer hard drive as should be) and now one under user name/library/cloudstorage/ - trouble is when i now click on dropbox in finder that has the files but all showing in cloud only - the other one is there but in a different place in finder - worried now about files on hard drive no longer syncing correctly - and the worst is the dropbox app with still not load at startup - could really use some help and advice
