Ask at /r/techsupport. Or better just take a look in the New, if this a mass problem there is a chance somebody already asked about it.
I don't need support, I have fixed the issue, but I know hundreds of people was affected by this yesterday, so I was just curious :)
Can you elaborate what do you mean “dell update”? Laptops, servers, etc. and what kind of update?
Sorry. It is a laptop running Windows 11. I'm not that sure about all the updates, but I do know it flashed the BIOS at some point. I can boot it from an USB-stick though, so I guess the BIOS is kind of working.
