Random prohibit sign happened

So first off, let me mention what I’m running.

MacOS Mojave 10.14.5 Asus Prime Z390-A Intel core i5 9600k 16gb ddr4 3000mhz Sapphire PULSE Radeon RX 580 8GB GDDR5 Using NVME for main Mojave system

As I was working (web development), my computer got noticeably laggy and then it froze. I couldn’t click anything with the mouse and then boom! The computer automatically shut off. I turned it back on and then the stupid prohibit sign came on.

I tried going into recovery from clover menu but still the same thing.

I decided to add the boot flag -v to see what’s up and got this: https://i.imgur.com/dE4t1ma.jpg

Never had this issue once since I built this machine. The only way so far I’m able to access the system is using my installer USB with 10.14.3 plugged in and use that as the boot device from BIOS and then click on boot Mojave from Mojave in clover.

If the usb stick is out then back to the prohibit screen again 🤷🏻‍♂️

Someone please help me 🙏🏼 thanks.
