Syncing data stuck for weeks (beta M1)

I use Dropbox on two Mac M1 machines. 459 files do not sync (stuck in this state for >2 weeks). 
Problem: I don't have access to my recent files. As a small business owner, I can't rely on having access to the data I need if taking my laptop with me. 

 

Further, I often get error messages: either a) unable to start dropbox at the start (starting it manually, yes) b) file not found if I open pdfs in preview. The second time I clicked on them, they opened after a long time - while I marked them all for download to the machine. I think about transitioning to GDrive if there is no fix for this. I need to rely on the basic function of Dropbox and pay for this, but it does not work with the beta anymore. 

 

What I have done: 

*quit dropbox

* restarted the machine
* deinstall dropbox + restart + new install 5x >> same problem

 

additional info:

• I use Dropbox private plus
• Dropbox folder /Users/USER/Library/CloudStorage/Dropbox
• Use of latest beta version (installed months ago, should have indexed by now 😉
• Machine M1 Pro 2021 M1 Max 32GB Ventura 13.2 (with Dropbox problems)
• Machine M1 Pro 2021 M1 MacMini 16 GB 1TB Ventura 13.2 (without Dropbox problems)
