Judging by the amount of time it took to generate your Etrecheck check report, I'd suspect a failing hard drive. Boot into Recovery Mode and run Disk Utility > First Aid. If it reports error run it until it either reports no errors or reports that the disk could not be fixed.

Looks like no one’s replied in a while. To start the conversation again, simply ask a new question.

You probably will, neither Disk Utility or SMART is very precise at predicting when a disk will fail. The only other thing that could be slowing your disk is Little Snitch but it isn't running the your report. Until you replace the disk, keep good backups.

If you want to test first, install an OS on a clean external hard drive and test that to see if you it is still beach balling. That way you'll know it is the internal causing the problem.
