Runaway Process? Brand New MBP M1 Running Very Slow

I've had this MBP with the M1 chip for almost 2 weeks and I keep having this issue. I use Google Chrome for my job and frequently have 6-10 tabs open. I bought this computer to try to fix my speed issues, but I this machine keeps heating up, running a fan, and showing high CPU usage from kernel task, windows server, and messages.

Typically, I will have the following open at the same time:

Chrome, signed in with work account, 5 tabs

Chrome, signed in with personal account, 2-3 tabs

Messages

Notes

Occassion use of Preview to view images

Slack

That's it. Sometimes everything runs well, other times I'm stuck in a lagging slowness with the fan going. Last week, after Apple Care was no help, I removed Microsoft Office's auto-update process and altered Chrome so it only checks for updates every 2 weeks. I thought that fixed the issue, but here we are again.

In case this is relevant, I have night shift mode disabled.

My EtreCheck report says there is a runaway process. How can I figure out what it is? Thank you for any help!
