Remove the developer beta by restoring your device
To remove the developer beta immediately, you need to erase and restore your device. Then—if you have an archived backup—you can set up your device again from that backup.

Note that backups created while using beta software might not be compatible with older versions of iOS. If you don't have an older backup that was made using the current version of iOS, you might not be able to restore your device with your most recent backup.

  1. Check that you have the latest version of iTunes.
  2. Connect your device to your computer, then put your device in recovery mode with these instructions:
    • On an iPad with Face ID: Press and quickly release the Volume Up button. Press and quickly release the Volume Down button. Press and hold the Top button until your device begins to restart. Continue holding the Top button until your device goes into Recovery Mode.
    • For iPhone 8 or later: Press and quickly release the Volume Up button. Press and quickly release the Volume Down button. Then, press and hold the Side button until you see the recovery-mode screen.
    • For iPhone 7, iPhone 7 Plus, or iPod touch (7th generation): Press and hold the Sleep/Wake and Volume Down buttons at the same time. Don't release the buttons when you see the Apple logo. Continue to hold both buttons until you see the recovery mode screen.
    • For iPhone 6s and earlier, iPad with Home button, or iPod touch (6th generation or earlier): Press and hold the Sleep/Wake and Home buttons at the same time. Don't release the buttons when you see the Apple logo. Continue to hold both buttons until you see the recovery mode screen.
  3. Click the Restore option when it appears. This erases your device and installs the current nonbeta version of iOS.
  4. Wait for the restore to finish. If asked, enter your Apple ID and password, which disables Activation Lock. If the restore process won't finish, learn what to do.
After the restore finishes, you can set up your device from your archived iTunes backup, which must be from an earlier version of iOS
I think this should work for you. Need a Mac or PC with iTunes.

Thank you. I will try it, but will I lose the data on the machine?
It is very likely that you will-almost certain without an iOS 12 backup. However, I would recommend completing a full iTunes backup of your iPhone now so that when iOS 13 is released to the public, you will be able to use your backup to have all of your old files when you choose to install iOS 13. Unfortunately, until then (while on iOS 12) you will have to start with your iPhone fresh and be unable to access your iOS 13 backup.
