DRIVER_PAGE_FAULT_IN_FREED_SPECIAL_POOL (d5)
Memory was referenced after it was freed.
This cannot be protected by try-except.
When possible, the guilty driver's name (Unicode string) is printed on
the bugcheck screen and saved in KiBugCheckDriver.
Arguments:
Arg1: fffff980063cce40, memory referenced
Arg2: 0000000000000000, value 0 = read operation, 1 = write operation
Arg3: fffff88003e5a1aa, if non-zero, the address which referenced memory.
Arg4: 0000000000000000, (reserved)
