Second screen got disconnected after updating driver

I have VGA GeForce GTX1050 and my OS is ubuntu 20.0. after a few days of my last update which was last week, I disconnected the second screen for a few hours but when I reconnected the cable I didn’t get any signal from the laptop. at first, I tested the cable and monitor and they were ok then I read an article that a new update of Nvidia is causing a problem with the second screen. so I tried downgrading the update but couldn’t so I reinstalled my OS. after all of that the problem is there yet. so I don’t get a signal from my laptop to the second screen. and here the list of drivers for my VGA card:
