Windows 10: Bitlocker de-encrypt failed

I have an old Windows 10 laptop that I hadn't used for a while. When I powered it up around the end of July 2024 for the first time in a year, a Windows update was installed automatically which caused the hard drive to be Bitlocker encrypted, which meant that I had to put the 48 character key in every time I wanted to use it, which is not only tedious but extremely annoying. The Bitlocker on the hard disk had never been used before,After looking for fixes to this after any August updates, I realised that I could turn off the Bitlocker encryption by logging in as Admin and disabling it. It star
