My Windows 11 File Explorer freezes, when I take an action on my Dropbox files.

Since the upgrade of my computer on mid august, I suffer an unbearable bug with dropbox. 
Note that only the dropbox folder is making issues ; all options work well on the website, and that problme occurs ONLY while I'm in dropbox folder.

The issue
When I double-click on a subfolder, when I right-click on a file (in order to share it as a link for example) or when I replace a file (like copy/paste a new version), 90% of the time this file explorer window freezes.
If I let it runs, it may or may not eventually make the action after 1 to 10 minuts.
If, during this time, I open a new file explorer window and navigate into it until I reach Dropbox, the exact same problem occurs on this second window.

That makes Dropbox totally unusable to me, so I consider switching to google drive instead of Dropbox after many loyal years. My workflow is badly and painly handicaped by this bug.

I tried to uninstall and reinstall dropbox, to move it from a Sata SSD to an NVME SSD (and back), to update it, update windows, update nvidia drivers. I even udpated my bios.
I also tried to disable my firewall. 
Nothing works. 
I readed many other users topics encountering the exact or almost same issue.
I tried all suggested solutions in those posts i readed, but nothing worked for me.
I'm about to give up, but maybe will you have an idea to fix this. Last chance.
