Does anybody know how to get the Mac GlobalProtect client to update?

I have a Mac 10.15.7 which has been stuck in the GlobalProtect 5.0.9-15 update for months.

It offers to perform the update, I accept and click install, the notification then disappears.

Soon a callout box appears telling me the update is in progress and I will be notified again when it is finished.

That is as far as it gets. The update process never completes.

They should long in to the portal and Download the file. . Then after that you can run the file and choose to uninstall . Then run the file again to install
It will ask for the portal.
