[Bug 1750351] Re: (Thinkpad T470) Boot loop after update

Not really; the error not showing up is because the firmware doesn't report an error, but even if it did we can't necessarily tell the user anything from it anyway (it might not be breaking because of Boot Order Lock). Fallback is a "new" feature to fix other systems that don't remember how to boo

I really don't think you're affected by the same issue as the other bug. I see there's a BootOrder set (at least, once booted), and there's an ubuntu entry that looks correct, but that does depend on what you're supposed to be booting to. The screenshot you include says the system should be bootin
