Nothing to apologize for, I hope things are (getting) better for you now!

The AMD GPU should only be used if you explicitly choose to, by setting
DRI_PRIME=1 or maybe using a corresponding setting of your desktop environment.
Maybe the AMD GPU is only getting powered up accidentally, and the freezes
happen due to something going wrong while powering it up/down.

Please attach the corresponding Xorg log file, preferably captured after dmesg
has at least two instances of

 [drm] PCIE GART of 256M enabled (table at 0x000000F400000000).


You could also try modprobe.blacklist=amdgpu on the kernel command line, to see
if the freezes happen even if the amdgpu driver never initializes the AMD GPU.
