Your system has both thermal and voltage sensors and both can cause your system to go into CPU Safe Mode. This is where your CPU's clock is lowered to keep the system from overheating. This is when the Kernel process is consuming a lot of threads.
Most of the time we see thermal issues or a bad/disconnected thermal sensor. I would install a good thermal monitoring app to make sure that's not the issue like TG Pro using the free version will allow you to see the thermal sensors and fan.
A common cause is liquid damage into the keyboard or trackpad or on your logic board’s voltage sensor has failed or the voltage divider logic is bad.

Have you tried booting to Safe Mode? Is it still lagging if you do? https://support.apple.com/en-us/HT201262

@Ojaswi Jaiswal Please select the CPU tab, in the screenshot you added we see the use of RAM which is not so meaningful. Do not forget the Coconut battery screenshot, just in case, take the screen after you click on "battery info" button.

@Ojaswi Jaiswal Battery and sensors seem fine from the further info you supplied, as well as CPU which seems not to be throttled at all. In my opinion data are processed fine, no bottlenecks apparently. I agree with @rav_taylor and I'd also try how things work through the Usb port..a faulty flash drive or data transfer from the drive to the Cpu seem to be involved here and that's where I would focus. Just my 2c.
