"Disabling "Multipath Networking" in Settings>Developer on the iPhone did the trick for me." --hokilife https://developer.apple.com/forums/thread/737907?answerId=769217022#769217022

iOS 17.1 appears to me to have resolved this issue.

Is your Personal Hotspot enabled? If so: On your Mac: • Open Xcode.app. – Window -> Devices & Simulators: Select the problematic iPhone. – Connect problematic iPhone to Mac via USB. On your problematic iPhone: • Open Settings.app. – Personal Hotspot -> Allow Others to Join: Toggle Off. – Wi-Fi: Toggle Off. – Bluetooth: Toggle Off. ( wait for connectivity error to clear on Xcode) – Wi-Fi: Toggle On. – Bluetooth: Toggle On. • Disconnect iPhone from USB. Some notes: • The problem might be aggravated by having a SIM-enabled Apple Watch connected via Bluetooth to the problematic iPhone (both of which use the same cell provider). • The problem seems not to occur if you enable the Personal Hotspot before enabling WiFi & Bluetooth on the iPhone (ie - USB only hotspot). • I've filed a bug with Apple about this (FB13287330).
