I download almost all of the mods for Speedrun on 1.16, but three of them didn't work, but that's the least, the thing is that, when I click on the gold boots to create a world, the Minecraft becomes a normal Fullscreen and, I can't record with AMD Software that needs Borderless, and when I start a world, my controls reset to default, and last, these mods are overheating my PC, so some of these mods is very heavy, on 2021 never suffered from overheating problems.

That sounds like issue with StandardSettings, make sure to set them correctly following this: https://github.com/KingContaria/StandardSettings#readme

And when it comes to performance issues, thats hard to answer, if anything try deleting ServerSideRNG, because that is not necessary and can lead to some issues.

ServerSideRNG doesn't even open my Minecraft, it crashes instantly, so I already don't have and my GPU overheat, if these recent mods require so much of a PC, so I will just use the 2021 mods, which I didn't have any overheating.

Try using the MultiMC launcher if you don't already do. It works way better for me than the normal launcher, and it solved some mods not working properly.
