Hi, i have a very similar problem. My system is working with 4.15 and with 5.1.16 but not with other 5.x kernels:

The System does not boot with 5.x kernels. With 5.1.16 the gui system freezes sometimes but sshd and mouse is still working.

CPU: Ryzen 5 2400g, BOARD: AORUS B450 I PRO WIFI, X Server 1.19.6

Kernel 5.0.x not working (blank screen after boot)
Kernel 5.2.x ( x <= 9 ) is not working (blank screen after boot)

but Kernel 5.1.16 is working (mostly)!

Error LOG with 5.1.16:
