Blue screen of death

I HAVE NO KNOWLEDGE OF BITLOCKER AS I HAVE NEVER USED IT

According to the image provided, you need to enter a security key. Microsoft says at aka.ms/myrecoverykey, you can find the key at https://account.microsoft.com/devices/re... if it was linked to your Microsoft account. If it was linked to a work or school account, go to https://aka.ms/aadrecoverykey. Printout and USB drive options are available so I would look for any items. If you cannot access or find your key, you will have to reset your computer which will erase all of your data.

I’m sorry if this does not work or the outcome has disappointed you, I’m only young (teenage), or if it has you are very welcome.
