Thanks for taHave you ever cleaned the fans and fin stacks? Laptops tend to clog up from dust - especially if used on cloth surfaces such (e.g. bedspread, carpet). If you don't want to take the laptop apart, you can use compressed air and get most of it .
Also, does your laptop have more than one fan? If so, make sure all of them are running by inspecting visually or by airflow. If one has failed, the remaining one could run at max speed and make lots of noise, while not really being able to properly cool the "other side" of the system. CPU and GPU are usually mostly cooled by their own setups, with some limited balancing between them.

Some of this sounds like the Nvidia driver is crashing, leaving you with just the iGPU.
I'd suggest cleaning out all traces of all Nvidia drivers (past and present) with a third-party tool called Display Driver Uninstaller (DDU), before manually reinstalling. There are plenty of tutorials online on how to do it - just try to find a recently dated one.
In Optimus settings make sure you have games set to use the discrete GPU.

Seeing as your laptop is getting on in years, another reason why it might be overheating is if the thermal compound has dried up. I've seen intermittent crashing on some old desktop (Nvidia) GPUs where I fixed it by re-pasting.
Try to find some way to track the GPU temperatures, and if they're high and the driver is crashing, this could be the reason.
Disassembling a laptop to reapply thermal paste is on another level compared to a desktop GPU, though. Especially the thin ones are finicky.

I deleted al previous app with ddu as you advised, and lunched the game with the back cover opened, the two fans were working both without issues; the gpu temperature goes up to 75C° as shwon with msi afterburner.
Now i'm only left with 1 option wich is to replace the thermal past on gpu, something i would have done today but when opening it two screws that the one that holds the cooling pipes were damaged unfortunatly.
