I normally share my MacBook Pro 13 2018 (on OSX 10.15.4 Catalina) internet wifi connection to my iPhone XS Max connected directly with a usb c to lightning cable. But now it stopped working and I see that Iphone USB doesn't appear anymore in the "To computers using:" box.
I tried the solution offered here that says that I should add an new location under the network preference, with no avail.
I also checked the solution offered here but the answer I don't understand why suddenly I would need content caching to share my internet connection.
Bluetooth sharing works, but the speed is very slow. Belkin usb-c lan, thunderbolt bridge and usb 10/100/1000 lan do not work. I was wondering if my cable was the cause, but the iPhone appears in the finder and charges without problem
How do I get the iPhone USB to appear back in the sharing tab and resume internet sharing? Below find screenshots of my settings with my iPhone connected to the laptop.
