I was finally able to view the report....had to wait 20 minutes for it to load.
The hard drive appears to be Ok, but there is still a small chance it could have a problem that does not show up in the health report (rare, but it does happen).
The EtreCheck speed check of the drive shows speeds around 50MB/s which is not unusual for a hard drive, yet the EtreCheck report took 14 minutes to complete. The EtreCheck report does have a lot of log files ending in .ips (with .json in the middle of the name). This may be the problem or it may just be another symptom. I don't know what these .ips log files are as they just started appearing with Monterey. The contents may be viewable within the Console app, but I imagine they will not provide much information. The best I can discover is these .ips crash logs are for applications and not macOS itself.
I don't see anything else in the EtreCheck report that would normally cause a problem, but make sure all listed apps in the report are completely up to date. Your macOS is at least one update behind as well. Maybe try disconnecting all external devices in case one of them is causing a problem.
I would run Disk Utility First Aid on the hidden Container so all of the macOS APFS volumes are scanned. Within Disk Utility you may need to click "View" and select "Show All Devices" so that the hidden Container appears on the left pane of Disk Utility. Even if First Aid says everything is "Ok", click "Show Details" and scroll back through the report to see if any unfixed errors are listed. If any unfixed errors are listed, then run First Aid from recovery mode, otherwise you will need to erase the drive, reinstall macOS, and restore from a backup.
If none of this works, then I would suggest performing a clean install of macOS by first erasing the whole physical drive. I would recommend only restoring the home user folder(s) from a backup and instead re-install all third party apps manually by downloading their most recent versions. If you choose to restore your apps & settings as well from a backup, then you may just bring back the problem which is Ok if you don't mind possibly needing perform another clean install without restoring apps & settings from a backup.
I also recommend testing the clean install before restoring from backup and before installing any third party apps to see how it performs. If it is still slow under these conditions with just macOS installed, then it would indicate a hardware issue, most likely with the hard drive.
