You may want to use other linux box to troubleshoot your OpenVPN connection, as explained here.

I firmly believe the whole RPI accessories scene has become an obsession. At the price you pay for an RPI they are practically disposable items. Certainly not a medium to long term investment by any stretch of the imagination.
I agree, RPi 5, just a goddess thing

The hdd tower has its own ~7A external supply. It powers both the hdds and the SATA-USB bridge. It does not make sense to add a USB hub, and the manufacturer explicitly recommends not using a hub. Why add more USB in the mix? HDDs do not draw power over USB, they are externally powered.
Yes, I noticed this
Your hdd tower might be simply broken, or it might not fully cooperate with RPi by design, or maybe your energy suplier experiences some random nightly brownouts - so I would think that some little experiments may help to reveal the root couse of your problem in a better way than reading loudly the hdd tower manual - play with additional powered USB hub, maybe invest into small power monitoring tool like this, see if upgrade to LE 12 changed anything... from my experience sudden hdd "unmounts" are typically finger-pointing to some power related issues. -
This sounds like power problem (despite the fact that your HDD tower is self-powered) - maybe some power peaks at night etc. I would suggest to add some reliable powered USB Hub between RPi and HDD tower (like this) and see if that makes any difference.

What does fail to initialize ptp_kvm mean? What is wrong?
Nothing, it just means that this kernel version is missing that patch, feel free to ignore as recommended here. The ptp_kvm features are used for VM time sync, definitely not your concern here

It is a brand new cable.
that's not the point - did you try some of these troubleshooting actions from the url which I provided? eventually you may gather more insights of your problem following these attempts...

What should I do next?
This seems to be a popular problem, see for example here. It looks like you need better hdmi cable.

This also did not work for me.
dmesg | paste - this shouldn't be too big, so as far as your RPi has network access it should work
for large kodi.log you can split it for chunks smaller than 512 kB:
Bash$ cd /storage/.kodi/temp/ $ split -C 500k kodi.log ksplit_ $ find . -name "ksplit_*" | xargs paste -i -
unfortunately it simply returns with the prompt.
It happens usually when log file is huge, pastebin has limit of 512 kB

I cannot provide something that did not exist (repeating myself). The RPi4 crashed multiple times, and by crash I mean that it was inoperable to the point that it required me to reinstall LE over and over again.
one option is to take out the disc (or microSD) from just crashed RPi4 abd mount it in another Ubuntu machine, then restore logs - see here for some ideas
-
don't use any scrap parts
Well, I used official RPi 3A power supply and without addidtional PSU my 500 GB ADATA SSD worked only on USB2 socket, while it was not recognized on USB3 sockets, so after all I'm good, but perhaps I had just some luck here.
RPi5 seems to have more power juice on USB sockets, this is might be another reason to wait for it.
-
The SSD drive does not have its own PSU.
You may also check if connecting via USB2 changes anything - I found out surprisingly that USB2 sockets on RPi4 provide more power than USB3 sockets.
-
That doesn't really seem to be helpful to me.
really? there are few more suggestions on this thread than just new hdmi cable
for example hotplug trick.besides there is also guidance there how to create and post full debug log, which seems to be your next option here

I installed LibreELEC-RPi4.arm-11.0.3.img.gz using the LE installer on my MicroSD 128GB but my system is just telling me there is "No Signal on my HDMI 2 port".
Probably dead microSD - check your LED flash codes as described here.

The power button works pretty much as on a PC: if you press it for a shot time it'll do a graceful shutdown and if it hold it for 5s it'll do a hard poweroff (needed when the system/kernel completely locked up).
They claim that RTC that can wake up your Pi from sleep mode and it’s programmable - I wonder if that also means that remote can wake it up easily with some setup...
-
However this plays nicely with LE12-nightly, so I suppose this is the way
