Mac crashes randomly

Hi. I'm running 10.14.2 on a custom desktop. Here's the specs:

MOBO: ASRock H110M-g/m-2​ SSD: Kingstone 240GB (Mojave), Team L5 Lite 240GB (Win10)​ CPU: i3-7100 @ 3.9GHz w/ 8GB DDR4​ GPU: Sapphire AMD Radeon RX 580 8GB​ 

I've managed to successfully install Unibeast on the SSD and the system can boot into macOS pretty easily and without hiccups. I've noticed though that sometimes, pretty much randomly (but often while using Safari) the system crashes and restarts on its own. Here's the pastebin of the crash log that appears when the system reboots: https://pastebin.com/JitTZJP7

Can someone help me fix this issue? Thanks.
