Loosing the update overlay button

"choose from the camera drop down menu “none” then choose lightburn camera"

This generally indicates a flaky USB connection pushing the whole camera interface over the edge of madness.
I had a perfectly serviceable camera that worked fine for a year, then started misbehaving for no obvious reason. After working around the problem for far too long, I swapped the camera cable for an identical cable from a different camera and it’s been working fine ever since.
So, by and large, you won’t go too far wrong by assuming the worst of the cables & connectors between the camera and the PC.
