Dropbox won't install on new Mac Studio M2 Ultra

When I set up this new Mac though, everything from my Macbook Pro came over automatically. On that laptop I had 2 users and always, always permission errors. I don't know how many times I went to the username folder and fixed read/write permission w/all enclosed folders and it never fixed 100%. I think having dropbox, google drive and icloud all installed complicated this somehow but I never figured out how to fix it for keeps; I always had to do it over and over. That's the sole reason I only have 1 user now. I say this because I suspect some of those complications carried over somehow. I have gone to the root folder of this new computer and checked, but saw no issues.
