========================================
So June 22, I was just playing normally Genshin Impact when it crashed midgame. The screen turned black all of a sudden but I can still hear the background playing in Genshin. I tried to close my phone then override it with error fingerprints and then the screen went back. After that, I tried to play COD:M, PUBG and LoL Wild Rift but did not really encounter these kind of issue. Then the day afterwards, I played my daily routine and booted up Genshin Impact. The issue occurred again and did the thing what went successful before. I uninstalled Genshin Impact then reinstalled it and ran it, the same issue occurred but this time, it was worse than before. The screen did not turn on even if I overrode the fingerprint scanner. I tried to memorize the power off settings and turned my phone off. I turned it back on but still the screen is black and is not showing me anything. I tried the long press thingy of the Air Triggers and showed proof that it was working fine. I searched it up online and tried the recovery mode but even if I did that, it's now showing anything throughout the process. It's been hours and now I do not know what to do anymore. I'm using my laptop right now.
Note: I turned the real time info settings on game genie but the cpu and gpu usage were not spiking up to 50%. The max for cpu was at 45% and gpu stayed on 20-30%. Phone is now 9 months old and very healthy until this problem occurred.
