I would like to ask for help with the development of drivers for the windows kernel.

Explanation:
I'm getting nullptr after calling: ExAllocatePool2, for an input of 108 Bytes

I've read several topics and by default I've already disabled all verifiers (1. cmd | 2. verifier | 3. Delete all)
Note: I am a beginner in the area, for this reason after buying the reference book, I am trying to complete this specific tutorial.

Setting Key Setting Result
Enviroment              VMWare Workstation
Free RAM              4GB Free


The code:

The command:

Attempts already made:

Can someone please help me?

Thanks,
Lucas P.
