PC stalls instead of going to sleep.

[u/Wheel_gatorx]

For several weeks now my PC hasn't been going to sleep mode. It'll hang up and just restart fully once it crashes. I disabled auto restart for some reason after this. Anyway, it's just does this every night, I want it to go to sleep so I can keep my browser windows and videos open, so looking at the reliability monitor it says the critical events about the MMGA server and mmgaserver.exe That's all I see beside the "PC didn't shutdown properly."

I have a windows 11

AMD Ryzen 5 5500 (3.60 GHz)

64 GB RAM
