CPU underclocking when under stress

Laptopl: Acer Nitro 5 AN515-55
SNID: 11002133634
CPU: Intel(R) Core(TM) i7-10750H CPU @ 2.60GHz (4,20 GHz max)
RAM: 32 GB @ 3200 MHz
GPU: NVIDIA GeForce RTX3060 (85w)

Windows 11 Home x64
BIOS version: V2.06

So like the tittle says, my CPU is underclocking when under stress, I've had this problem for quite a while but I've been able to work around it, but I'm getting tired of the random FPS drops when playing games.
I've recently updated my OS to Windows 11 but I've had this problem for around 6 months or so while using Windows 10, it started with weird underclocks right from the computer start, the clock speed would lock at 1,80 GHz but after a restart it would go back to normal, and after 2 weeks or so the problem was gone, a month after, whenever I would start any resource intensive app (even games like War Thunder that only make the CPU usage go to 60~%) the speed would go from 4,20 GHz to 3,70 or so and stay there, restarting the PC wouldn't fix it anymore and it's been like that for 5 months now, updating drivers, cleaning and updating the RAM as well as changing the thermal paste didn't work, also tried to change the settings on the energy plans and no fix either, I've noticed something weird tho, the fan speed on the Nitro Sense app seems to be quite slower for he CPU, although I don't think this is the problem, the CPU used to go up to 90° when gaming when I bought it, now it rarely gets to 80° or 70°, because of this the fans rarely get to high speeds on their own too, but as shown later on this post, a single core seems to be hitting higher temperatures than the others, which isn't shown by Nitro Sense or any app that gets the temperature of the CPU as a whole.

Another weird thing is that even tho the CPU reaches it's max speed of 4,20 GHz the speed seems very unstable, jumping from 3,90 to 4,45 and inbetween constantly, these screenshots were taken seconds apart from each other

Now here's a screenshot of the CPU being stressed by CPU-Z.

As soon as the CPU hit 100% usage the speed dropped to 3,70 and slowly kept going down to 3,60, after 1 minute went down to 3,50, but as soon as the stress test is stopped this happened:

The speed picks up as if nothing happened, weird behavior was noticed in the voltage used by the CPU, and using Core Temp a single core seems to go up in temperature very quickly

 

Running normally

Not even 1 second after stress test starts

If anyone knows how this problem could be fixed, please let me know
