I can’t leave the Minecraft RTX beta

I have found a solution. After I deleted my original insider account I created a new one and joined the rtx minecraft beta other than the nether beta which was what I was in. I then updated minecraft to rtx and unenrolled and reverted back to the normal
minecraft version.

Hi! I understand you have tried uninstalling an reinstalling, but it also depends on where you install from. I suggest unenrolling from the insider program, an doing a hard reset [how to hard reset. Hold the power button on your console for ten seconds than
wait then turn it back on] that should help, than go to the Minecraft store page and installing from there.

Let me know if this helped

Uninstall the game beta, go to the hub insider and leave the beta content, go to the store and installed your game version normal

You will need to opt out of the beta and wait until it shows you are no longer signed up. Then uninstall the game. Remove your account and do a hard reset on the console. Once you switched it on again then readd your account and download the game again.
Should be able to get the current public release of the game.
