My iPhone 13 Pro Max internet connection freezes after wifi is disconnected. I thought it was due to bluetooth connection, but it happens without connected headphones. I have to do a forced reboot to gwt the internet connection working again. I tried resetting the phone, of no avail. Any tips?

When I try to sync my iPhone 13 Pro Max (iOS 16 beta 2) to my MBP M1 Pro (Ventura beta2) it gets stuck in step 3 of 5 (preparing to sync), the back-up (step 2) gets created. I mainly use this to get music form my Mac to my iPhone (yah I know, old school, right.. hehe) Any tips?
