Windows 10: Why is Local Security Authority Process lsass.exe using so much CPU and memory?

Whenever I use my laptop Dell XPS 13 9300, lsass.exe uses a ton of my memory and CPU, to the point that my fans are always going at maximum speed. I've found a couple other forum posts about this issue both here and on other websites, and none of the help they gave me has solved the issue. I am running Windows 11 formerly Windows 10 where I had the same problem. What can I do to potentially solve this? It's extremely bothersome as it slows my laptop down significantly and causes it to be noisy all the time. Any help would be greatly appreciated, thank you!

Should lsass be using a large percentage of my CPU?

'Local Security Authority Process' is using over 25% of my CPU at times.

In case it's needed information, my CPU is listed as:

'Intel(R) Core(TM) i5-6400 CPU @ 2.70GHz, 2701 Mhz, 4 Core(s), 4 Logical Processor(s)'

Is this something to worry about?

 

The security account manager (SAM) or local security authority (LSA) server was in the wrong state to perform the security operation.

What actually the process LSASS does and why it actually consumes a large amount of bandwidth quota?
