I've seen this issue before -- ironically on a System 76 laptop and *only* with Pop_OS (Ubuntu worked fine, at the time). It seems to be linked to a buggy version of plymouth, or misconfigured drivers in the initrd. I never really figured out which. But it seems that the laptop did boot, only with a blacked out display. Booting from alternate media was successful, and I could always force my way into the installed OS.
