UE4 (10.1) release channel broken and doesn't compile

The release channel of UE4’s source code appears to be FULL of errors, I’ve not changed anything and compiled but i get a tun of errors and no compiled engine. I’ve restored everything to default and even restarted my pc… still nothing. Epic your engines great, but it would be grand if we could compile the stable branch. Thanks

Here’s the errors I’m getting

edit: For anyone else running into this issue, simply delete the Steamcontroller folder, that seems to have fixed it for the time being.
