Hi ,

When the next public version of iOS or iPadOS becomes 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.

As you are obviously an Apple developer, you would have received the instructions for downgrading when you signed up for the beta program, but if you need a reminder, see: How to uninstall iOS or iPadOS beta software - Apple Support
