No Apps Running other than EtreCheck
Unless there is absolutely nothing listed under Kernel extensions, launch agents, launch daemons, user launch agents, and login items, there are always apps running.
I suggest you uninstall those two kernel extensions first. Then uninstall dropbox. And maybe install com.motionvfx.mInstaller.HelperTool.plist too. I don't know what that does, but you are running out of things to remove.
If, after all that, you still have a problem, then it is probably a hardware problem.
The file system test just creates a bunch of small directories and files, and then deletes them. At a file system level, that is pretty much all your machine does all day long. It normally takes 30-40 seconds to run. The test cancels itself it it runs over two minutes. Antivirus software and "sync" software are the software that seems most likely to interfere with these operations. Any kernel extension could do that too. There is no separation in the kernel between software tasks. Anything can interfere with anything else.
This is probably a hardware problem, but you won't know for sure unless you get rid of all the 3rd party software. Wiping the entire machine and reinstalling the operating system is a good test, but most of the time, people do a restore, as you did, and put all the 3rd party software right back. That's a waste of time as far as debugging goes.
