I certainly could be wrong here, but I simply don't see how this can be hardware unless something is overheating. (and it shouldn't be possible to cool things down so quickly that a simple reboot fixes it.)

You can try a CMOS reset, which ought to put everything in the BIOS back to factory defaults. I can't imagine that it will make any difference.

Given that it can affect opening files in programs as well as windows explorer, I'm wondering if it's related to an antivirus program somehow.

If this were linux I could offer more concrete suggestions, but not with windows unfortunately.

It's Windows 10 with the built-in Windows Security antivirus only, no crazy software installed.

I may try resetting the CMOS however the defaults already include all sorts of AI stuff turned on from Asus, which was part of what was so annoying about their BIOS. I just want everything OC-related OFF. There isn't even a clear indication of what RAM setting equates to that. There's XMR, XMR2 and two other settings and none of them are labeled like "factory default" or "just use the out-of-the-box timings". It's the curse of buying a mid-to-high-end board that has tons of features I don't really want or need, but happens to have the right I/O ports for my needs.

Another weird symptom observed: I am downloading a large file and noticed it was taking forever and only getting a tiny fraction of the bandwidth available on my pipe. I have a large file transfer also occurring on the local network, from one mapped drive to another, each drive physically located in a different box, neither drive in this PC. I paused the network file transfer (which was only ~56MB/s, about half what I would have expected as I usually transfer files on the LAN at around 100MB/s) and the download from the Internet immediately picked back up to where it should be at around 12-15MB/s. I've never seen that sort of bandwidth issue before, where one causes the other to slow to a crawl. And the two combined are not maxing out the normal bandwith of the network. So again, the issue appears to be related to something with this system's Windows install or system drivers or BIOS configuration, where something isn't configured properly and isn't running at full capacity..

I also notice that while the large file transfer is going on on the LAN, it is also causing this computer to be more lethargic. Which is odd because the files are moving from NAS to another, neither of which are physically attached to this PC. They are however on the same network switch and the file transfer is being performed through this machine in a sense, in a standard Windows file transfer status window from one mapped drive to another.

Windows Update with a pending install makes a Win10 system sluggish.

But like someone said earlier, Windows Defender makes the system slow down at times for no consistent reason.

I think I've narrowed it down to a memory issue. I'm seeing all sorts of lag loading/displaying things, whether embedded videos on webpages or Windows Explorer listing contents or status of drives/folders, when as little as 12GB of the 32GB is in use. I will have to run a MemTest and also try swapping around/out the RAM.

edit: Well, the RAM won't run in XMP or XMP 2 (even with trying to manually bump a few voltages recommended on Asus forums), so it's stuck with 2133Mhz anyway. Nothing I can do about that. MemTest didn't show any issues, and the sticks are in slots 2 & 4 as recommended by Asus. Guess it's just a cursed build at this point.

There is a known issue when right clicking for menues that contain 3rd party options. I know troubleshooting one in windows explorer was a real PITA. Once I cleaned up junk links in the registry mine started working much faster. But there is still random right clicks when using Win10 where it never seems to finish bringing up it's menu. Funny thing is there is no rhyme or reason when they occur.

Update: I think I fixed it by swapping the RAM. I was on Corsair 2x16GB CMK32GX4M2E3200C16 which would only run in SPD setting.
I just replaced that with Corsair 2x16GB CMK32GX4M2D3600C18 which runs XMP 2 settings. Everything is much snappier. Nothing feels lethargic.
Amazing what a slight difference in RAM model can make. I chose the latter set because it's on the latest QVL for the board, and the other set wasn't despite being so similar. Wild.
I'll post again if the lagginess returns but this already feels a lot faster in responsiveness all around.
