Windows 10: bit locker key lost to a deleted account

Today I was randomly prompted to provide a bit locker key on start up for my laptop. I do not recall enabling this feature myself.I think my laptop was connected to a school microsoft account, which I graduated nearly 3 years ago. And since then my university has deleted this student account. I have checked all my personal microsoft accounts and this laptop is not connected to any of them. It is probably connected to a microsoft account owned by my previous school, which they have already deleted. I also check my alumni microsoft account given from my university, just incase it was transfered

Bit Locker Key

Daughter laptop requesting bit locker recovery key.

She didn't change anything.

But overnight, its now requesting this. So assume an update occurred, that impacted this.

Ive checked our MS account and there no recovery keys there. He device is not even listed.

Is there a workaround, or fix. Ive looked at the support notes, and don't have a print out of the key or usb stick etc..

any help would be appreciated. As were stuck on the blue screen Bit locker screen.
