Windows 10: Bitlocker says it unlocks the drive then I get a method error???

How do I deal with the problem documented in this log? The log says I successfully unlocked the drive, then I get an InvokeMethod error. I previously unlocked this drive last July.[2025/05/17 20:43:35.428][Info][1] Unlocking Bitlocker on volume D. [2025/05/17 20:43:35.525][Info][1] Executed IsNumericalPasswordValid with returnCode 0.

HELP: Automatic BitLocker Unlock.

Thank you sir, ill try your solution.

Windows Auto unlock ONLY works in case you have Bitlocker on your system drive, because if your system drive is not encrypted auto unlocking other drives means loss of security.
But in my case my system drive is Encrypted with hardware encryption that i password unlock during boot. So auto unlocking Bitlocker drives will do fine for me.
