My comment there is outdated, I was able to use PowerShell this time when trying the solution again.

This may be due a temporary connectivity error, or a timeout occuring. You can try disabling Small Network Packets if enabled. Please see:

Otherwise, are you able to temporarly switch to a mobile data connection and check if the error persists? This can help to determine if the issue is ISP/network related.

Thanks! It seems Small Network Packets is causing the issue, I disabled it and was able to join a match, then I enabled it, joined another and I got the error again.
