Welcome to Apple Support Communities.
Notes from your EtreCheck report:
- Heavy CPU usage This may go away with a restart.
- No backup. It is very important to have a backup!
- High battery cycle count Your battery may be in poor shape.
Here's the odd issue:
Performance:
System Load: 5.73 (1 min ago) 13.31 (5 min ago) 17.46 (15 min ago)
Nominal I/O speed: 1.92 MB/s
File system: 120.61 seconds (timed out) (Terrible score)
Write speed: 584 MB/s (Good score)
Read speed: 917 MB/s (Good score)
So, something may be amiss with either your SSD, macOS Installation, or User Account. I would suggest you make a Time Machine backup [Back up your Mac with Time Machine - Apple Support], and try to Reinstall macOS: How to reinstall macOS - Apple Support.
Also, what does DriveDx say? I see that DriveDx may be installed.
