All other devices in home will connect to WiFi except phone. The VPN on the settings page keeps glitching and won’t turn on. Updated a bunch of apps and now the phone will not connect to WiFi and YouTube says “Not Connected” regardless with LTE on. Not seeing any decent replies from Apple on this one so far.

VPN frequently creates more problems than it solves. But one important fact is that when you install VPN it configures itself to the specific hardware, iOS version and network that the phone uses. If any of those change it can break the VPN. So any time you change any of these you may need to delete the VPN app and profile, restart your phone then add them back. So if you need it and you reinstall it your iPhone should still work, until the next update.

First: Go to Settings/General/VPN & Device Management/VPN, tap on and delete the VPN profile. Then delete the VPN app.
Next: Restart your router. Unplug it for 15-30 seconds; many newer routers have no real power switch.
This was 100% the solution. I had to use my phone hot spot for my work laptop (which requires a VPN). It must have forced the VPN onto my phone.
