SOLVED: Cannot see local Windows drive (want to add video source)

I'm currently on the latest LibreELEC Beta. I've installed LibreELEC on a USB flash drive connected to an Intel NUC with Windows 10 OS in its SSD drive (using UEFI boot with both OS). In this Windows drive, I've videos which I'd like to watch via LibreELEC/Kodi. The problem is that I cannot add them as video sources as the LibreELEC seems to only see one partition of the drive (sda2-ata-'ssdmodel'_C17) and there's nothing in it (EFI, FOUND 000, System Volume Information, ._DS_Store, BOOTSECT.BAK). The odd thing is that earlier this year I did manage to do this (I could boot to LibreELEC USB and watch videos in the Windows SSD drive) but at some point something must have gone wrong as I couldn't do this anymore (it's as if the file path was broken or LibreELEC stopped seeing the drive). If memory serves, I did not change anything in Windows and going over my BIOS settings, there is little I can change to help the matter. I'm 100% certain I did not use any terminal commands in LibreELEC.

Anyone got any ideas? I know LibreELEC should automount drives but for some reason I cannot access my Windows files.

You sure you fully exited Windows? Not that it's in hibernation or sleep mode?
Also doublecheck your SSD for errors and fix them. Linux can be very picky about them.

Well, considering I've set my NUC to boot straight to USB LibreELEC and that I always power off after use, Windows shouldn't be sleeping or hibernating. When I want boot to Windows, I always open the boot menu upon power on and select Windows. Anyway, I do remember that when it was working I did try some tricks to make the USB LibreELEC see the C drive on Windows SSD, but cannot remember what they were (I did try disable/enable secure boot/legacy mode in BIOS but to no avail). I've gone through every menu on LibreELEC but see no option to make the C drive appear. I am in the Windows 10 Insider Program meaning constantly get new builds so it's possible this is some sort of weird bug (surely Windows doesn't have anything I should change so that it's visible as a local drive). However, as I've understood that LibreELEC should automount drives and as I had to something I cannot remember before to make the C drive visible, it makes me think this isn't a Windows bug. I've also checked the SSD for errors so that's taken care of as well.

I guess I just have to boot to Windows everytime I want to watch the videos I have on the SSD drive.

Lots of blabla, and I still don't see any of my requested listings.

'Friendly' neighbor, eh? Forgive me Klojum as I wanted to try and solve the issue without going into measures such as you suggested (I'm unfamiliar with using SSH and commands). Anyway, I did manage to finally solve the issue. I noticed a setting in the NUC bios called UEFI Shell which was turned off (as it's the default setting). I turned it on, booted to USB LibreELEC and saw the C Drive with my files. For what it's worth, other BIOS settings which can be relevant were (Legacy Mode: off, Secure Boot: off, enable USB along with UEFI Shell via Boot Configuration).

I should really look into SSH and those commands but haven't had the time to learn but the basics of OpenELEC/LibreELEC/Kodi.

UPDATE: The problem came back. I decided to go with the latest Alpha build (having used the old Beta release from the get-go) and now everything's working. It's funny how the Beta release is promoted as a stable release which most people should use while Alpha builds are promoted as unstable. However, many seem to go with Alpha builds and now, after trying the latest build, I will not be going back to 'stable' Beta builds.
