System Data taking 30G on iPhone 12

I’m on the iOS 18 Beta 1 with my iPhone 12. Since I only have 64 gigs on this phone, storage is sometimes an issue, though I can normally decrease it by getting rid of apps. As of downloading iOS 18, though, “System Data” is always taking half of my storage. Because of this, I am unable to update to a newer version of iOS 18. It also sometimes prevents me from taking photos, where I then have to restart my whole phone to get a little bit extra storage. Is there any way to update without the storage, or some way to decrease System Data?
