But however now its letting me play beat saber with no lag and no problems after I deleted and reinstalled beat saber

And what I noticed is that anytime my Oculus quest 2 has a update it takes my modded version of beat saber and instead if saying something like unknown source and please restore, it didn't and all my mods were still there but if you delete and reinstall is will say unknown source please restore.

I hope this helps and I hope those: Restore Beat Saber to the Oculus store version pop ups go away
