I'll also remove beta profile from system preference
please give me solution
Remove macOS 12 Beta Completely
You can't revert to an earlier OS. Only thing to do is turn off beta updates and allow the official release version to catch up to your beta.
Revert. Erase your storage, and restore your most recent pre-beta backup.
Or wipe the storage, and perform a clean install of Big Sur.
Otherwise, you're on the beta until it goes into production.
macOS doesn't have downgrades.
Don't install betas with hardware or apps or data that needs to remain available.
Run betas with copies of production data where production copies are permissible, and with test data, and with test systems.
