Good info that. And good sleuthing!

Obviously it indicates there is some problem with your regular user account. The trick is figuring out just what the problem is. I'm not sure how to track that down.

Short of discovering what has affected this account, you could try to reinstall macOS from Recovery mode.

In this case it's simply laying down a fresh copy of the OS without doing any erasure of any sort. This process leaves in place all of your user files and info.

Still, the first thing to do before reinstalling macOS is to backup your files onto an external drive. Use Time Machine or other backup option such as Carbon Copy Cloner or SuperDuper!

Once you have your backup done, you can boot the computer into recovery mode and reinstall macOS.

Another option would be to transfer your current files to your new user account.

I think the easiest way to do that would be copy all the folders and files from your home folder to an external drive, then copy them back into the home folder of your new, working user account. Once you have your files on the external drive you'd want to delete the old account along with its home folder to free up the storage so you can copy the data back into the new user. The reason for copying your folders and files to an external drive is to strip the ownership attributes from them. When you return them to your startup drive they will inherit the ownership attributes of your new user account.

TBH, I'd give the macOS reinstall a try first.

Good job getting this report posted. 👍🏽

To my eye things look pretty good.

I don't see any of the usual suspects like third-party anti-virus or cleaning apps.

I see you have just under 200 GB of free drive space available (189.35 GB) which is fine, barely. To allow the OS to run properly you don't want to allow your free space to get below ~150 GB on this 1 TB drive. A good rule of thumb is to maintain ~15% of the total capacity free at all time. So, keep an eye on yours going forward.

I also see that your drive write and read speeds are healthy at 3645 and 3718 MB/s respectively.

You don't have Time Machine enabled. That won't affect performance, but you do want to have some sort of backup of your stuff if it's at all important to you.

Your 16 GB RAM doesn't appear to be under much pressure since there haven't been any memory swaps used. But 16 GB really is not too much when running today's complex apps.

Your recently installed apps appear to be from Microsoft, Adobe, Google, WhatsApp and Logitech. Nothing shady there.

You do have some daemons that have been eating CPU cycles: spotlightknowledged, mediaanalysisd, photoanalysisd and photolibraryd in particular would be expected to do that for maybe a few hours or days after installing an OS update/upgrade. That should settle down before long.

The OneDrive app has experienced high CPU use. You might look into that a bit deeper.

Other than this handful of things I don't see anything that should be causing your Mac to become unresponsive.

There are others here in the Community who can parse this report much better than I and I hope and expect that they will step in and add to the conversation.

Do you happen to have a Time Machine backup of this Mac?

If push comes to shove and you need to migrate the data from the problem user to a fresh admin user account, it would come in handy. In fact, at this point, even a clone backup done with Carbon Copy Cloner by bombich software or SuperDuper! from Shirt Pocket software could be helpful.

Our friend, @Tesserax, addressed migrating data from one user account to another on the same Mac in this thread: My MacBook Air won’t accept correct passw… - Apple Community.

I think you will want to take a look.

You're welcome.

Yes, I can say that the hesitation and delays that are evident in your video are not expected behavior.

The drawing of the different System Settings windows and panels should be nearly instantaneous under normal circumstances.

There is something going on there with your Mac.
