After update to MacOS 13.5.1 my external monitor was not detected by my MacBook Air

After the update, my monitor (LG 32UN880-B) and the attached hard drive and ethernet adapter stopped working on my 15-inch MacBook Air.

The MacBook will not even charge when the monitor is connected. A connected iPhone works fine on both interfaces.

Nope. I had the issue previously with MacOS 13.0(?). Was fixed with 13.1.
