I'm with MatteN on leaving the fancy enhancements turned off (with my 65B7V) unless you like movies to look like camcorder footage. It does sound most like a software issue on the LG side though.
Worst case you could run Kodi natively: https://kodi.wiki/view/HOW-TO:Install_Kodi_for_webOS
If you can run CE from USB then you can run LE, but you will need to trigger the recovery boot process (same as installing CE for the first time) else the box is configured to look for CE boot files which are different to LE files. You'll need to repeat that each time you flip between the two OS.
abws update to https://test.libreelec.tv/12.0/Amlogic/o…droid-c2.img.gz (wget to the /storage/.update folder and reboot) and then update the repo again. We switched ARMv8 compatible boards to "aarch64" so "arm" add-ons are no longer being built and pushed to the repo - although there was a config error in the change so the AMLGX image remained on arm until last night. If you cross-grade to aarch64 the repo should exist.
Current LE images should boot from USB in addition to SD cards, but current LE images run kernels that don't have drivers for the i2c tuners found in Android boxes of that era (USB ones might work, but not i2c). Older LE images only support specific boxes (not yours) and CE hasn't supported GXL boards for some time either. In short.. 
I'm not sure what a Home Hub is? but if something is connected between the Pi and the TV, remove it and connect them direct to prove the connection works as expected without it. If it does, you can point fingers at the Hub device. If not, I would try a different HDMI socket on the LG as sometimes TVs are preconfigured for a certain content type on certain sockets. If that makes a difference: a) you have a workaround, b) you can point fingers at the TV firmware. LE does not otherwise send any HDMI content-type signalling that would cause the TV to detect/change something so there is nothing to adjust. The sole exception is when HDR media is being played, when we flag the Cinema (not Game) HDR profile. There is no equivalent flagging for non-HDR modes.
That output on the UART console means there is no bootloader on eMMC, which is a good thing as you can safely experiment with different GXL "board" images (see https://wiki.libreelec.tv/hardware/amlogic) on an SD card to see if anything boots. The (limited) GXL images we have are for VIM(1), Lafrite, LePotato. You can probably try the VIM2 GXM image too as GXM is a GXL derivative. If anything boots, let us know.
tomaszc Thanks for the tip-off. AMLGX images should have switched to aarch64 (not x86_64) bakck in October but something was missed. This should fix that when merged https://github.com/LibreELEC/actions/pull/71 .. I rarely use the official AMLGX releases (as I have my own) so hadn't noticed 
I've edited your post. If users want to install torrent clients on their HTPC the use-case is obvious and not something that we are keen to have discussed in detail in this forum.

IIRC this ^ also provides DSD file support to Kodi (so no need for MPD) though this is not referenced in the add-on info text. If you can confirm I'll send a change upstream to add mention of DSD to the add-on.
This is not currently possible using the LE11/LE12 Generic (GBM) releases as Kodi doesn't support 90º rotation with GBM. However if you run the Generic Legacy (X11) version I believe it will be supported.
Google research on "pcieport aer corrected error received" hints at power management on the NIC device, and a few forum posts and such recommendations adding "pcie_aspm=off" to kernel boot params in /flash/syslinux.cfg .. remount the partition rw using "mount -o remount,rw /flash" .. there are other options to perhaps experiment with once you start reading things.
Free Man You need to manually drag/drop the LE12 RPi5 nightly image onto the creator app and then write the image to the SD card. There are currently no LE11 "release" versions (only LE11/LE12 nightlies) so there is nothing to select from the drop lists. RPi4 images do not work with RPi5.
I always confuse macOS (1m) with Linux (1M) so use "dd if=/dev/random /dev/mmcblk0 bs=1M"
Users get pissy when there is slow access to their data, so the OS compensates by opening the fileystem and caching data about the inodes inside to it's in a "ready to be accessed" state. If files are marked open/in-use and then the power is pulled, the filesystem is in an inconsistent state and will need to be checked and marked clean before it can be used again. Even if a system is functionally idle it's computationally always busy doing something (like checking it's still idle)..
Libreelec works very well, but in the bios I can not find the settings to change the usb power behavior when shut down.
Well, your original post contains ^ that statement. Cheap mini-PC boxes frequently have dumbed down settings, and if that's the case, there is nothing we can do to magic them into existence.
Do you have actual media in 4K60 formats? .. because outside of demo/test material it's a rare thing and 99/100 users trying to make 4K60 work (often with under-spec cables) have no real-world need for anything above 4K30.
Probably something in the file or encoding that causes the decoder to fault. You can re-rip the file from the original source with different settings, or perhaps run the current rip through handbrake to re-encode and hopefully normalise whatever the glitch is.
Do we have to guess the LE release? .. and how about a debug log?
