Your PC appears to be faulting due to an Asus related driver:
Invalid system memory was referenced.  This cannot be protected by try-except,
it must be protected by a Probe.  Typically the address is just plain bad or it
is pointing at freed memory.
Arg1: fffff88009300e00, memory referenced.
Arg2: 0000000000000000, value 0 = read operation, 1 = write operation.
Arg3: fffff880089ba9b4, If non-zero, the instruction address which referenced the bad memory
Arg4: 0000000000000002, (reserved)

By looking at the stack IOMap64 is clearly visible, but do you notice the pattern?

u fffff880`089ba641
fffff880`089ba641 413bc4          cmp     eax,r12d
fffff880`089ba644 0f847efeffff    je      IOMap64+0x14c8 (fffff880`089ba4c8)
fffff880`089ba64a 48c7060c000000  mov     qword ptr [rsi],0Ch
fffff880`089ba651 eb67            jmp     IOMap64+0x16ba (fffff880`089ba6ba)
fffff880`089ba653 443927          cmp     dword ptr [rdi],r12d
fffff880`089ba656 750c            jne     IOMap64+0x1664 (fffff880`089ba664)
fffff880`089ba658 488b05c13a0000  mov     rax,qword ptr [IOMap64+0x5120 (fffff880`089be120)]
fffff880`089ba65f 493bc4          cmp     rax,r12
If we unassemble the program code we can clearly see
that IOMap64 is being called.

lmvm IOMap64
start             end                 module name
fffff880`089b9000 fffff880`089c2000   IOMap64  T (no symbols)           
    Loaded symbol image file: IOMap64.sys
    Image path: \??\C:\Windows\system32\drivers\IOMap64.sys
    Image name: IOMap64.sys
    Timestamp:        Fri Feb 05 03:55:34 2010 (4B6B7A96)

By running the lmvm command we can receive more information about the driver. We can see that it is very outdated by looking at it's Timestamp.
Remove all Asus related software and utilities!
