I can not leave Minecraft RTX beta programm

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.

This has been a common issue within the RTX Beta. Be sure to check out the
Known Issues List and the Frequently Asked Questions for the latest details on this issue.

If you have xbox insider, check if you have entered the minecraft beta programm, if you, get out of the beta and reinstal minecraft

Iv'e tried to access the RTX beta for Minecraft but when selected it
wont download and just takes me to the Minecraft store page.

I also have both versions of Minecraft and got the newest version for free due to having the Minecraft Xbox One Edition.

If you un-enrol from the beta version you will have to reinstall Minecraft to get the version that isn't part of the beta programme. You won't be charged for the game, the only change will be that you won't be able to go on the worlds that you previously
created or saved on the beta version since it will have the beta features.

If you ever decide that you would like to play the beta version again, you can join the beta programme on the Xbox Insiders Hub then reinstall the game again to have the beta version.

Hope this helps and happy mining
