My wife's 13" Retina MacBook Pro (late 2013, Intel Core i7, 2.8 GHz, 16 GB RAM) is also stuck at a black/blank* screen during the upgrade from Catalina to Big Sur. The machine can be turned off by holding down the power-button, which makes the screen turn off (i.e. completely black), but when it's turned on again (i.e. pressing the power-button) the screen goes back to being black/blank.
I have tried resetting the SMC and the NVRAM, but this doesn't change anything.
Any bright suggestions?
* No image is displayed, but you can tell that the panel isn't off, as it is when the machine is powered off.

This worked for me, too. MacBook Pro mid-2014 13" Retina was stalled for hours with progress bar showing half way. After it restarted, Big Sur was installed and asking for sign on.
Thank you very much, t5vag! This also worked on a 2016 MBP 13 with the touchbar.
Could you inform about replace ? Could it helped?
same issue
I had the same problem on a MacBook Pro 15" Mid 2015.
But your solution works. I'm so happy :-)
Thank you.
TX, this did the trick for me!!!
Same thing for me.
Thanks and a Tip of the Hat!

Please update us since we also have the same issue..
This also worked for me - definitely worth giving a go.
I updated my 2013 MacBook and days later it would not turn on. Logic board was gone. Major repair for something Apple did to my laptop.

I hope you found a solution for your issue.
Thank you for your generous insight, William.
I suggest you open a ticket with official Apple support, if you did not do it yet or eplehuset in Norway
didn't do it for you.
