Hey folks, I have evidence that this is something busted on Postman’s server side.
My personal account: totally unable to load workspaces on postman desktop, on two different machines, on different networks. Not firewall/websockets related. Issue survives signout, total wipe of preferences, etc. Developer console shows a bunch of errors relating to the sync store on the busted account.
I set up a fresh account with another email — no problem.
I deleted the original account, and then created a fresh one — no problem.
FYI.
