Postman not starting up - stuck in preparing workspace

I guess i am still having issues.
I had tried to update my win10 box again (from the 6.7.4) version, which i can install and it will work.
But if i try to upgrade it or install the latest version or install the latest canary version.
Then i cant seem to get past the ‘preparing workspaces’.

I un-install (deleted the local data / roaming) folders.
But i am assuming that there is something else (maybe a registry value?) that is preventing me from getting past.

My old win7 box, had no issues updating to the latest version.
And i really wanted to check out some of the great new features.

Thanks again.
