Protools 2021.3.1 slow to load and then freezes
 

I have been using Protools since version 10 (2013). I had not used it for a couple of months and since then have upgraded Windows to the 20H2 update and ProTools to version 2021.3 and then 2021.3.1. I have also cloned my C (boot drive) to a new larger SSD drive, and replaced the 6Tb data drive that was a RAID (2 x 3Tb drives) with one single 6Tb drive.

Now it is very slow to load and then hangs on getting to the dashboard, freezing if I try to do anything on it.

I have completely uninstalled ProTools and reloaded it, uninstalled and reinstalled my audio Drivers, gone through all optimisation procedures, deleted the database and Workspace files, I have even gone through other suggestions such as checking for disks in the CD/DVD drive - all to no avail.

Any other suggestions would be gratefully received.
