AN515-45 GPU half-broken (?) - probably hardware issue

Model: Nitro AN515-45
I think it was after GPU update - May update last year - that dedicated GPU (geforce rtx one) just stopped working (it's only integrated working now). In device manager two things have yellow warning triangle: 1) geforce rtx gpu (Code 43); 2) NVIDIA Platform Controllers and Framework (Code 31)

I tried installing many versions of GPU drivers: the version before update, some older versions and even the vga from acer website. I was using also DDU with different options and NVCleanstall. Always the same problem. I even used new disk and installed fresh windows.
I tried also that trick with holding power button for 1 min with unplugged charger.

MY conclusion: it's rather hardware issue since even fresh windows with fresh drivers didn't solve.
I also checked gpu visually and it does not look any "broken-ly", but I m no expert in hardware.

Last 2 images were made yesterday after reinstalling gpu drivers with DDU.

TLDR: GPU not working but it's (probably) not a software problem (because fresh windows installation didn't help)

    Welcome @JustLemmeConnect,

    This is a strong sign of faulty dedicated GPU, cracked BGA solder, damaged VRAM chips, defect in one of the VRM circuit phases, or corrupted VBIOS.

    Is any of this easy to diagnose by myself? And is any of this "worth" repairing (I mean, worth in money terms)?

    Only a technical service specialized in laptop repairs will be able to tell you with absolute certainty why your GPU has failed.

    In terms of costs, reballing procedure and replacing VRAM chips may be more affordable than replacing the GPU chip.
