I ran this etrcheck tool and attached the report. I'll appreciate any tips anyone can offer.

the etrecheck report did not show up here. if you'd like us to look at it, please copy the report again and paste it into the window using the additional text button below.

Well, several things stand out:

1. you only have a minimal 8 GB RAM
2. you have a fusion drive which means you have a small SSD and a very large, but 7200 rpm spinning (and therefore slower than an SSD) hard drive
3. you installed CleanmyMac. Uninstall. Worthless, unnecessary, and may cause havoc with your system.
4. you have webroot. Why? See #3.

FYI, starting with Catalina, your OS and system files are "sequestered" on a separate, read only, not accessible by you or anyone or anything else making any cleaning or AV software utterly irrelevant. Also, I am not familiar with webroot, but I would guess that it may not be compatible with the security processes of Big Sur. In any case, either or both of these can cause havoc on your system including slowdowns. So, I would suggest you uninstall both according to their uninstall instructions and then see how things are running. You can also add more RAM by going to OWC (macsales.com) for additional RAM including install videos.

You can also remove/delete all items in your Login items - not necessary; apps will launch when necessary.

Try these suggestions and see if things are running better.

So, did you want help interpreting the etrecheck report? If yes, you need to post it.

Or did you solve your problem?

You need to uninstall CleanMyMac and Webroot. Both are not needed and cause problems. You only have 8GB of RAM which is minimal for Big Sur. Adding RAM should help.
