2026-05 Security Update (KB5089549) (26200.8457) - Another failed installation

Basically, I haven't been able to install the last 2 or 3 security updates - the installation keeps failing. This is happening on two relatively new machines running Avast, while on two older computers, I installed the updates without any issues, and they are running the default Windows Defender. Does anyone know what the problem might be or why the installation has been failing for the past 2 or 3 Security Updates? I read somewhere that Windows changed something regarding BitLocker, but I don't see why that would cause the installation to fail.

Bitlocker recovery key not able to find.

After updating my windows a bitlocker recovery key is asked every time I tried to boot up my laptop. I don't remember when did I enabled secure boot and where did I saved my bitlocker key.

I checked with all microsoft account I have, in none of the accounts I am able to find the key.

I even tried disabling secure boot from bios settings. Still bitlocker key is asked everytime upon system bootup. I tried restarting my laptop several times as recommended by some users, it didn't fixed my issue.

I have brought the laptop recently and moved all of my personal data including pictures, videos and documents to my laptop. I don't have any backup of my personal data.

I am seeking for any help other than resetting the laptop as it will erase my entire data stored in laptop.
