Hi rodger_rulez,
Thanks for using the beta and reporting your experience. In this case we'd recommend using the included Feedback app to mention when you're experiencing. However, here's the instructions on how to go back to the most recent publicly available version of iOS on the device:
1. Go to Settings > General, and tap VPN & Device Management.
2. Tap the iOS Beta Software Profile.
3. Tap Remove Profile, then restart your device.
When the next public version of iOS or iPadOS is available, install it to move back to a non-beta version of iOS or iPadOS. If an update is already available, you can install it by going to Settings > General > Software Update, but the iOS or iPadOS version must be later than the version you have.
If you don't want to wait for a software update to install a non-beta version of iOS or iPadOS, follow the steps to restore iOS or iPadOS.
You can find the full resource here: How to uninstall iOS or iPadOS beta software
We hope this helps.
Take care.
