'Failed to connect to lvmetad' after changing Grub

I have Ubuntu 18.02 installed on my Dell XPS laptop (single boot) with an encrypted disk.

But when I try to boot I get the error:
Failed to connect to lvmetad. Falling back to device scanning.

Earlier today (when I still got into Ubuntu) I changed through '/etc/default/grub' the GRUB_CMDLINE_LINUX_DEFAULT configuration, I added resume=<swap_partition> in an attempt to get hibernate working.
So I assume this change has something to do with the boot issue.

I tried through an ubuntu life usb to get to the grub file to change it back, but I cant find the right disk (see link to pictures below).

Any change is greatly appreciated, I need my computer for work tomorrow, and dont know what to do.

Edit

Questions:
1. Is it likely that the above change I made to the /etc/default/grub causes the Failed to connect to lvmetad problem? Are the two related?
2. How do I get into that grub configuration from the live usb?

That should be /dev/sda1! – George Udosen Dec 07 '19 at 20:24
@GeorgeUdosen thank you! I see it is mounted on /cdrom. I am not sure how from there to find the /etc/default/grub – Kemeia Dec 08 '19 at 03:14
@GeorgeUdosen /dev/sda1 is not encrypted so I think this cannot be the disk that I am looking for – Kemeia Dec 08 '19 at 09:42
