I found the app sandbox was the problem, thanks to [this](https://forums.unrealengine.com/t/has-anyone-been-able-to-get-online-subsystem-steam-to-work-on-a-mac-apple-silicon-in-ue5-3-1/1353483/2)

Just had to remove App Sandboxing in Xcode by clicking MyGameProject-\>Signing and Capabilities and then the trash icon.

Graphics are still bugged, but steam overlay at least shows.
