Mac Desktop app won't open after migrating my user profile from an older Mac

[boardmad]

Mac Desktop install has started to fail on open after moving my user account and profile over from an older mac to a new MacbookPro M3 Max. I have read som of the similar messages in the forum and followed the uninstall/reinstall procedure. Help appreciated?

App fails on open with following error message text

Hi @boardmad, thanks for messaging today!

If you're not on a Dropbox Basic plan with more than 3 devices connected, could you try an advanced reinstall of the app using the steps in this link?

Keep me posted!
