Got my Air 8,1 with Mojave installed and everything was fine. Added a Razer Core X / RX 580 and everything was fine. Installed Catalina and everything went to pot 
Applications randomly closing and opening when i didn't want them, the device actually crashing/restarting and sleep issues.
So it got to the point that i had had enough, i wiped it and put Mojave back on. Everything is fine except sleep issues. It won't come out of it at all like it used to do before i installed Catalina and i have to mess with the power button untill it wakes up.
This has me wondering - is the reason it has sleep issues is because the Catalina EFI is at fault?
