I used a brand new SD, formatted it, and then used Etcher to burn PlexPi 1.3 image to the disk.

When I booted up my Pi3B+ loading stopped at the following line.

1.140248] ---[ end Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(179,2)

Any guesses what happened or how to fix it would be appreciated.

I guess your SD is damaged or the downloaded image is corrupted. Try to download the image again and reflash it on your SD. If you get the same error, I think you can try a different SD card
