MacBook Air doesn't recognize iPhone SE

I'm trying to sync my iPhone SE running iOS 18.5 with my MacBook Air running Sequoia 15.5 but now the laptop doesn't see the iPhone. It doesn't appear in the Finder window as it did before. I've tried everything suggested by the community, restarting both devices, turning off VPN, allowing device connection when unlocked. The "Trust this computer" prompt appears on the phone, but no response from the computer at all.

This phone used to connect fine. I suspect a phone or Macbook software update is the culprit.
