Dropbox Desktop App won't connect (Apple Silicone M1)

Hi Megan 

Hi Megan,
 
sadly the same result as above. No solution to my connection issues.
 
Here's what I did:

1. I did follow Walter's steps.
2. I was asked to reinstall the app after starting it from my Applications folder.
3. After installing and logging in to my account on my Macbook, the app said that 3 devices were already connected to it (iPhone/iPad/this Macbook). So I did remove the MacBook (old device ID I guess) in favor for the newly detected MacBook device ID.
4. I once again ran into the connection issue. Here's the German screenshot and its translation. Plus the .txt-file containing information for the Dropbox support.

Dropbox could not be started.

This may be a temporary error. Please restart Dropbox.

If the problem persists, please contact Dropbox Support with the following information:
