Lag on MBP 16

my MacBook Pro 16 (core i9 2.3ghz, radeon 5500m 4gb, 1tb storage, 16gb ram, bootcamp partition) is lagging recently, I haven't downloaded anything im just doing my normal work like surfing the internet, using discord and stuff. I noticed its been very laggy on everything, from the animations to loading times. its especially obvious on YouTube I did a screen capture of the problem down below. it basically froze and recover after 10 seconds, and it even lags when I do nothing, like im watching a YouTube video and it just freezes for a couple of seconds. its clearly not YouTube as its system wide and I can't even use alt-tab during the freeze period. and the login times have increased too. Also on discord, the loading cursor pops up for like 10 seconds. this behavior on such a powerful computer is absolutely unacceptable and I only had I for barely over a year. plz help :(

To leave Safe Mode, choose “Restart” at the bottom.

Safe mode prevents your Mac from loading certain software when it starts up, including login items,

system extensions not required by macOS,

and fonts not installed by macOS. It also does a basic check of your startup disk,

And it deletes some system caches, including font caches and the kernel cache,

which will be created again automatically as needed.
