I can't minimalize my Minecraft or else it crashes (not in the automatic way)

What I expected to happen was that I could access the desktop and go back to Minecraft.

What actually happened was when I tried to pull Minecraft back up, it crashed. Rarely, I can get Minecraft up and it takes forever. Most of the time, I try several times to get it back up and then when I try to close it it takes forever and when it's about to close, Minecraft will pop up, and then close down. I'll add a video file showing it soon.

Steps to Reproduce:
1. Press the minimalize button on Minecraft.
2. Try to bring Minecraft up.
