I have the same problem. There is a bunch of GL-related logging that doesn't look fatal and then it just logs this over and over:
0308:err:wininet:open_http_connection create_netconn failed: 12029
Presumably it's trying to download some extra content or just check for updates.
12029 is ERROR_WINHTTP_CANNOT_CONNECT which has something to do with inability to establish a secure encrypted (https) connection. Maybe the server it's connecting to has had its certificates expire or something like that.
