This has been repeatedly answered, by multiple contributors, throughout this thread...

If you are currently enrolled in a beta programme and wish to return to using the current production version, this support page provides the necessary information to remove the beta from your iPhone:

Be aware that restoring an earlier version of iOS will completely reset and erase your iPhone. Assuming that you have a pre-existing iCloud or iTunes backup of your iPhone that has not been updated since installing the iOS 26 beta, your locally stored data and files can be restored after returning your iPhone to iOS 18.5; if you don't have a pre-existing backup, all locally stored data will be irretrievably lost:

An iCloud or iTunes backup can only be restored to a device running the same or later version of iOS than created (or last updated) the backup. As such a backup created or updated by iOS 26 cannot be restored to a device running iOS 18.5.
