UE4 Games minimize to desktop upon launch

This happens across many ue4 games that I have tried, Fractured Space (4.8), The Mean Greens (4.10), and H-Hour: World’s Elite (4.8.3).
When I launch the game and it is set to fullscreen mode, it will minimize the game on my desktop or just give me a black screen which I have to power cycle my monitor to get out of. It will also happen sometimes when I alt+tab. This only happens to me when I launch the game in fullscreen mode on my monitor.
I never had this problem when I was using a 60hz monitor. It has happened on multiple system builds going back to when I first got my monitor in august. I don’t have teamviewer installed on my system.

I attached dxdiag and log from one of the games that gave me issues. The code below is part of the errors in the log.

Hi xSneak,

Unfortunately, this is an error that would be best discussed with the developer’s of each game. You can find their respective sites below:

https://www.fracturedspace.com/

It happens some of the times I try to launch unreal tournament from the epic games launcher also.
Thanks for trying to deny it is a software bug with the engine itself despite ample evidence.

Have you posted this to the Unreal Tournament forums in the Bug Reports section? This can be found /forumdisplay.php?74-UT-Development-Bug-Reports-QA

I have discovered that if you have teamviewer running and attempt to open UE4 games, they will minimize. This is a known issue and we are looking into it, but do not have any information as to which program is causing the error to occur, if this is what is causing your error, turning off teamviewer will resolve the minimization.

Having said this, the error in question is most likely not editor related, though it may be something that must be accounted for when using UE4. If you have an editor specific error, such as the minimization occurs on a project created in UE4 when launched in standalone mode or after packaging, I will be more than happy to assist you further.
