Can't open Dropbox on new macOS Sequoia 15.2 - it does't respond and closes

To be Clear:

I am on a mac Version 15.02

I uninstalled as recommended on the website for mac uninstall

I reinstalled this download. "Dropbox 214.4.5217.dmg"

Upon open, the dropbox app repeatedly opens the dropbox website in 5 second intervals to install drop box on the mac. Then when I try to install, the app says it is no longer open. The loop of events goes on infinetly.

I try to turn off System Settings>General>Login items & extensions, and dropbox turns it back on by its self.

Hey Shelski. As a test, can you try to install a previous version of the Dropbox app instead and let me know if you face the same behavior/message?

I tried, still not able to load the dropbox application

Thanks for clarifying that for us Shelski - as a last step before we take this to email, could you maybe try creating a new OS profile and let us know if you were able to install the Dropbox desktop app normally? 

I created a new user profile and got the exact behavior. I click on the dropbox icon in the menu bar, it disapears. Next, I open the app in applications and I get a pop up saying - The application “Dropbox” is not open anymore. Then the Icon reappears in the menu bar, and disapears with any mouse movement.

Further, if this helps:

 I started work on the computer and this popup appeared. I granted permission, but no change

This is the popup I get when I right click the icon ibn the menu bar.

Left click does nothing. After a few seconds, the icon disappears from the menu bar.

Hi Shelski, is this a personal machine or a company-managed device?

Have you made any changes to your default browser on your machine? As my colleague asked earlier, have you got any special VPN, proxy or firewalls running?

Personal Machine. I use Chrome as default browser, but when I created a new profile I kept everything as is, no other installs and Safai as default browser. 

No special VPN, proxy or firewalls.

Could you try performing an advanced reinstallation again, and this time use the offline installer on this page?
