This screams hardware issue. I can't say its the M92 but there are ways to check it by opening up and meassure certain points on the motherboard.
EDIT: If you can open it up, take out the battery and plugin the charger and see if it starts.
Sadly you need someone with knowledge of soldering to exchange the m92. It seems pretty easy to change for those with knowledge since its a fairly common chip as well.
M92 is part of charging circuit and it can die randomly at any time. It also blows up if the charge is wrong from the USB-C, why people jokely call it the "M92" fuse instead of the proper fuses on the board.
@The Real Jdbye, I thought about that and I have blank DVD's and Blurays but honestly after like 90 songs I just listen to it a couple of hundred times toss it out and burn something else or have like 2-3 CD's. Florida here the heat in the car tends to ruin the CD's after like a few months even commercial pressed ones don't last too long.
