THEY CAN'T KEEP GETTING AWAY WITH IT 😩
Yet another Windows 11 update has caused issues, this time fortunately it was identified and patched very quickly via a rollback. The problem it caused seemed to be with apps that used the HTTP/2 protocol, which isn't quite as common as regular old HTTP, but still common enough. And apparently it especially affected apps that used "localhost" to connect within the same computer, but I think it affected other apps too.
Here's the command with the shortcut in the bonus tip I mention at the end:
powershell.exe -command "& {Update-MpSignature -Verbose; pause}"
