Using AirPlay with Sequia error 501 (AppleTV Apple Vision Pro)

I have a 2011 MacBook Air that I was able to install Sequia OS on using the Opencore legacy patcher. Everything works great on it with barely any lag (it actually works better than Sonoma!). However I’m having an issue with the mirroring / airplay. I can airplay my iPhone to my Mac with no issues for example. But when I try to mirror my MacBook to my AppleTV or to my Apple Vision Pro (so I can use ultra wide screen) it gives some sidecar error.

localhost SidecarDisplayAgent[3309]: [com.apple.sidecar:display] Encountered unrecoverable error: [Error Domain=SidecarErrorDomain Code=-501 "SidecarErrorVirtualDisplayFailed"]

Does anyone know how to fix this? Thanks in advance 🙏

Note: I’ve tried logging out of iCloud on both devices. Tried renaming the devices. Made sure on the same network. Receiver is enabled on both
