Hi, good day! I'm John Dev a Windows user like you and I'll be happy to assist you today. I know this has been difficult for you, Rest assured, I'm going to do my best to help you.
When was the last time it worked properly?
It seems the attached link of the video isn't loading.
Do you have a secondary monitor connected? If so, please try disconnecting it and see if the issue persists.
If this doesn't work, open the said program then Press and Hold the Shift key on your keyboard. Right click the affected program on the taskbar. Select Move then use the left and right arrows on your keyboard to move to the center.
Kindly let me know if this helps or if you have any further concerns.
