Windows 10: Bitlocker Recovery won’t accept my password!?!

I am using windows 11 and am stuck in Bitlocker recovery mode. I have accessed my recovery password from my microsoft online account but the I am getting “The password failed to unlock volume C: “ Does anyone have an answer as to why my password would not be working. It is a 48 digit numerical password. My issue is that I was using my laptop, closed it and went on my way and a couple hours later I went to turn it on and the Bitlocker recovery blue screen came on. All systems have been checked and passed all tests. I am assuming it was an issue with an update. Is there a work around this? Ple

BitLocker won't accept correct disk password after... something

The company I work for has computers with TPM chips and Windows 10 Enterprise, and uses BitLocker for full-disk encryption. They have BitLocker configured to require a password at boot (which I believe means the TPM is not involved in the decryption, and the disk should only be encrypted by the password itself; is this wrong?).

A coworker has his computer off the network for a while and they removed his computer's access. To get access back, IT had to do "stuff" to it.

In the process of this, they had to

• Make BIOS accept USB boot drive
  
• Do something, maybe including updates to stuff (they weren't able to explain what the thing they ran did, only that it "did stuff")
  
• Boot the computer
  
• Noticed BitLocker password wasn't working
  
• Went back into BIOS and re-initialized the TPM (because "sometimes that makes it accept the recovery key")
  

But the BitLocker password still didn't work... and the extraordinarily-competent IT people (the same ones who re-initialized the TPM) also lost the recovery key from their database.

What is actually causing it to reject the correct password?

Is the TPM relevant to this at all? (does password-protection require both the password to be correct AND the TPM to have the correct PCR state, or is it independent of the TPM?)

How can he unlock the drive with the password? (if the above question is that it still requires the TPM, then this is probably a worthless question because it's impossible)

 

Bitlocker passwords don't work with certain symbols but accepted

Has anyone else come across this problem? I used the symbols '/' and '#' within a Bitlocker password to allow the user to avoid using the shift key. These symbols were accepted as a password change. At the next login the password was refused as it was 'incorrect'.
I had to use the Recovery key to get in and change the password again. Bitlocker says you can use symbols and doesn't list exceptions; this sounds like a nice Bitlocker 'bug'?
