So I recently installed Windows 10 and I was having trouble,
basically when I pressed ESC and wanted to alt+tab I was getting this annoying black screen bug.
I found a solution for that but there was another problem, the IM:RP Launcher, then I realised how to fix it on my own just basically follow the instructions on the video.
Credits goes to the video publisher aka "Nasif I" and the owner of the following thread according to "Nasif I"

About the IM:RP Launcher part, it's easy; simply press right-click on it,
Properties > Compatibility > "Run this program as an administrator" Apply & Okay, voila.
This worked for me however,
If you're still having any problems with it you can ask something down here or just simply make your own search using google.com, enjoy.
