I don't see any software problems in the report except for the high System Load. Google Chrome is known to use a lot of memory & CPU resources, but during the report collection Chrome seem to be almost idle.
Try running Disk Utility First Aid on the SSD. You may even want to run First Aid on the Container instead by clicking on "View" within Disk Utility and selecting "Show All Devices" so that the physical drive and Container appear on the left pane of Disk Utility. Even if First Aid reports everything as "Ok" click on "Show Details" and look for any unfixed errors. If you find any unfixed errors, then it will require erasing the whole physical SSD to create a fresh file system before restoring from a backup or clone.
It is possible you are encountering some sort of Big Sur issue.
