Ouch, there is no result on using the ls -R command it should show all folders and subdirectories. Actually, it's very hard to troubleshoot this issue without the device on hand.
Maybe even the dir command does not show anything?
Have you ever tried to check the folder directly without using a terminal shell? If you can then you can right-click the tar file to extract or open a terminal on that folder.
I can't think more about how to fix this but I have my last option I think you can try to install Bitcoin core through snap check the guide from this link below.

https://snapcraft.io/install/bitcoin-core/raspbianHope this one will work.
Other than the fact that I would never recommend installing software from snap for several reasons, I don't see how it can work if it was developed for raspbian and we have a chromebook here
I also agree that installing from Snap isn't recommended and IMO should be used as last resort. However Bitcoin Core (Snap version) wasn't developed specifically for raspbian. That link mainly show
how to install Bitcoin Core (Snap version) on raspbian.

What if I bought a rasperry pi or blitz, would that work with my chromebook?
Raspberry Pi is a computer, i doubt that's what you want. Meanwhile Blitz (i assume you refer to RaspiBlitz) is created for Raspberry Pi. As i said previously, you should try download Bitcoin Core tarball file
inside/from your VM.
