Bare-metal hardware freeze in NexisK development

Hello everyone,
Could anyone assist me with an issue I have been encountering recently?

I am a low-level software developer working on NexisK (project repository: https://github.com/icarotelesdasilva/NexisK).

I am facing a specific issue in unreleased kernel commits that I have not been able to resolve:

1. The custom bootloader loads normally.

2. The bootloader menu displays correctly.

3. Upon pressing Enter, the system successfully transitions to 32-bit protected mode and enters VGA text mode.

4. Immediately afterward, the system freezes completely, with the VGA text cursor blinking indefinitely.
   Steps already taken:
   Removed the GDT post-bootloader phase.

Stripped out most critical kernel routines and services, among other diagnostic attempts, but the issue persists.

I have attached a video demonstrating the behavior.

If anyone is willing to help investigate, I can share the uncommitted codebase branch reproducing this bug.

Thank you in advance for any insights.
