Hello guys. After updating UnityHub to 3.1.1 I can't longer login to my account. Please help :(

After the update when I press the login button in Unity Hub, it opens a blank page on a browser.
I checked Firewall and AdBlock.
Also tried to log in to my account on site before logging through Unity Hub. Didn’t work. And also vice versa.
It showed me this:

“message” : “Conversation Not Found”,
“code” : “132.191”,
“details” : [ {
“field” : “cid”,
“reason” : “Conversation 942928e9-c440-495b-a724-04aba23918ba010f not found”
} ]

Make sure that you have selected Programms for all types of Web Files;
