Same error here using a Lenovo Yoga X1 3rd with fully updated Ubuntu 20.04 (focal). I can confirm the problem is not fixed yet.
Removing "quiet splash" seems to work and also observed (when I was trying to debug this) that pressing Esc key in early boot stages to avoid splash screen and see the boot logs also workarounds this incredibly annoying bug too.
