Dropbox app stopped working on Ubuntu 22.04

Today I booted up my fully updated laptop, Ubuntu 22.04, and noticed dropbox didn't start automatically. I manually started the app but nothing happened. I rebooted and tried again, nothing.

Then I uninstalled dropbox and reinstalled (using the latest deb package for Ubuntu 14.04 - 22.04). After this install I got a message from update notifier that a restart of nautilus was required for dropbox. I clicked the restart button and nautilus did indeed restart. Then I got a button that says "start dropbox". I pressed it and again nothing. Again a full reboot and nothing. Again reinstalled and rebooted, nothing.

I tried using the dropbox CLI. Navigated to my dropbox folder and ran

$ dropbox status
Dropbox isn't running!

Then I tried

$ dropbox start
Starting Dropbox...Traceback (most recent call last):

    raise child_exception_type(errno_num, err_msg, err_filename)
OSError: [Errno 8] Exec format error: '/home/jens/.dropbox-dist/dropboxd'

I have no idea what the issue is. Any help is appreciated. Let me know what other info I can provide for diagnosis!

Thanks!
