Rewards disappeared and uphold wallet permanently disconnected

Hello,
I am no longer able to see my Brave Rewards i have accummulated over the past few years.
The balance is now 0 and the Uphold wallet is disconnected - when I try to log in to Uphold from the ‘disconnectd’ link on the brave rewards page, a new window opens and then it goes white and does not respond. Nothing loads.
When I go directly to Uphold website and click log in, same thing happens - new window opens, goes white, nothing loads. url is https://wallet.uphold.com/login
I am on Windows 10 Enterprise and using Brave V1.30.86 (Sep 28, 2021)
Please help!
THanks

Anybody else here have this problem or know how to fix it? Support is silent so far…
