Dropbox keeps crashing and restarting itself in an infinite crash loop

Hello,

I'm also experiencing this problem. I've tried configuring my firewall to allow Dropbox, and disabling the firewall altogether. I have no other antivirus programs. I ran the terminal command to check for symlinks, but there were none. I also uninstalled and reinstalled the app.

Most of the time the desktop app will just open and crash on loop. If I quit the app while it's booting, I receive this message. Any personal information has been replaced with [removed].
