Raspberry PI 4 blank screen after splash screen

I’m not sure this applies to you, since “the same problem” could cover several possible cases, but there was a partial workaround provided a few days ago for devices that aren’t connected to HDMI: Headless Pi boot failure - #3 by fzinken

It’s partial in the sense that it only works for (no-HDMI) headless devices where the Kodi GUI isn’t required.
