cat /proc/meminfo gives detailed memory usage info.
sudo vmstat -s is less detailed but easier to read.

This is a pretty good look at it on KDE

Thatās the one I had in mind 
If thatās what telling you that swapās in use - well, I have no experience with that reading anything but 0 - like so:
34399228 K total swap
0 K used swap
34399228 K free swap
0 pages swapped in
0 pages swapped out
so I guess Iām not useful in this context! Good luck - hope someone has a solution for you.
Itās hard to tell if it happens in windows as well - it jumped from staying at 31% memory usage to 35%, then back down to 33%.

This is just from about 30-60 minutes of uptime.
Which kernels have you tried?
Iām going to try downgrading to 5.8.7 now to see if that works.
Also try linux-lts.

You can compare it to mine side by side. If i had to guess i would question what software packages you have installed. I am running kde and it is flawless. It is so fast and so responsive.
On my system i have BTRFS installed without luks encryption using @2000 guide with timeshift and snapshots.
The only packages i have installed
korganizer
thunderbird
chromium
gimp
gparted
rhythmbox
celluloid
lollypop
spotify
libreoffice
simple screen recorder
pamac-aur-git
qbittorrent
vlc
package-kit-qt5
All EndeavourOS Apps From the Repo
I wonder what software packages you have installed? Is it a software issue?
Your list is huge compared to mine.
It sounds more hardware-related given that
Have any idea what might be causing it?
Iām just asking because there arenāt that many components. If memory is tested, and video card changed and cpu? Cpuās donāt normally go bad. So we are left with the motherboard, power supply or drives which i doubt. If it isnāt the install which i canāt confirm? Then?
Edit: It also doesnāt make sense if itās hardware then you would see the same behavior on Windows.
If it was me i would test the power supply properly, the drive with a utility and reinstall. If after all that then your only left with the board. I would be running it in Windows to see for a good length of time to verify.
Iāve heard first-hand instances of where the PC case was causing weird issues. I donāt rule anything out any more.

Howās that??
Accidental static electricity or something like that?

I think it was something to do with EM fields - the case worked fine with a different set of components. It was truly, truly weird.

I donāt like whatās going on at all. I mounted my NVMe (which I use for games and pictures) to try to resize it for another EndevOS installation butā¦
Bam. 1 TB of data gone in an instant.
I doubt you have EM fields in your PC case which are strong enough to affect your computer.
Maybe it was grounding. A long time ago, I had an improvised, homemade, wooden PC case, and grounding was a problem on it, since wood is not a very good conductor. 
I think the fans generated static charge in some of the components. Connecting all the screws (of hard drives, motherboard, back panel, etc) with copper wire and running it to the case of the PSU fixed the problem.

Well i guess that points in some right direction what the issue is. So if youāve lost everything then you wonāt have any option but to do a fresh install. I would just try a new m.2 drive and install on it. Or reinstall on that one but you better wipe it clean and test it.
Edit: You said you have two drives? So is that just your Windows drive you are talking about? 
I have three drives: Two SATA SSDs, one windows, and one linux, and my m.2 SSD that I store most of my files on. My EndevOS install froze when I booted it up after testing my Windows install. Think my PC doesnāt like it when I boot up different OSes. But man, Iām so out of ideas. Iām probably, at this point, just going to replace my mobo and possibly RAM, and wipe my Linux install. Once I reinstall EndevOS, Iāll install my original programs bit by bit and keep all of you updated on what the culprit is.
I do have a question though: Could Windows 10 possibly be causing this, even if itās on a different drive?
It really should havenāt anything to do with it as far as Iām concerned unless you have done something funky with the installs.
What does your fstab show.
