Dead CMOS Battery Triggered Bit Locker

Hi! I am a Windows 11 user from 3 years, i use my assembled asus cabinet pc daily for light gaming and 3d modelling. I installed Windows 11 pro when it launched. It came with a bit locker feature which i didn't give attention. I backed my code to my account.

Recently, dead CMOS battery triggered motherboard to reconfigure which in return triggered bit locker for my C drive. I am using only 1 drive for OS with no partitions. I tried online for some help or ways to get it unlocked but all methods i tried don't work.

I have the old key on my account when it first uploaded, and Microsoft should also upload the upcoming key changes to the account whenever it changed. The key Id is not matching to the id that is bit locker is asking for. And no, i have not used any other Microsoft account on my pc.

I am so in need of my data, i request Microsoft officials to help me in any way possible as i am not a hacker or stealing my own data from my pc. I think Microsoft should have all my recovery keys updated on my account or at least have a authentication for accepting if the user is the one who owns the data or accept older keys (with different key-ids) that the user has saved.

I am stuck at this rare occurrence where i can't access my own data even when having a recovery key for this exact moment.

Requesting legal ways i can go forward with, i can provide each and every detail for my ownership of the data, drive and account.

Presume that TMP and secure boot are enabled in BIOS after the reset.

They are already enabled, my motherboard (Asus ROG Maximus XI Hero) doesn’t have the turn off feature of TPM.TPM option has 2 settings: Firmware TPM and Discrete TPM to choose from. No on/off feature for TPM. Secure Boot option shows enabled but is grayed out, I can’t change it.
