Bios update deacviated windows, now can't find windows activation license key

[Blarg3]

HP recently released a BIOS update that deactivated my copy of windows 11 and also stopped TPM from appearing.  This was all over the forums, a bunch of users were upset at the problem... a DOS box would ask you to push Y or N to start windows with TPM or by clearing it out or whatever.  

Trying to solve it, I wiped out the laptop and installed windows 11 fresh.  EVERY Time I've done this, with dozens of computers, they "find" the old Windows license and self-activate.

I went through FOUR cases with Microsoft.  They said they can't recover my digital windows product key.  They said I have to contact the OEM, HP, to get the product key for windows originally attached to this computer.  

1) I'm furious over HP killing my windows and TPM with another faulty BIOS update... they did this to my desktop also 

2) I can't find any option to contact HP and get the windows Oem license attached to this laptop. 

Help! And never by an HP computer again, their BIOS updates are a MENACE.

HP,  help, I can't find any help or contact info online.  Can you help me find my Windows OEM license key based on my motherboard?
