if you ever used a second monitor for your windows laptop or pc, it can be possible that after you disconnecting one of your screens and when you open some of your programs it will not show up.
The reason is because it used to be opened on the other screen. now you got 2 solutions.
connect back your other screen and drag and `drop` your program to the other one
press alt + tab and stay on the program that is open on the other screen. with holding alt press space and the (holding alt) press m. then if ex: your second screen was on the right and your main screen is on the left press the left arrow button and your program should show up.
