WebView crashes in authorization popups

I'm trying to connect to a Azure Data Explorer (Kusto) source on a completely fresh install. You can try this for https://help.kusto.windows.net/ but I've had the same problem with our production data source as well.

When I click on sign-in a popup shortly flashes and closes again. Then it just reads: "We're unable to connect. Please delete your credentials and try again later."

In the trace I've found the following Exception:

I've validated this problem on 3 different machines with the most current May 2022 version. I can also send you the full Diagnostic Information Dump, but I can't upload it here...
