Hello Leckbir,



Thank you for writing to Microsoft Community Forums.



For further clarity on the issue and to guide you accordingly, respond to the questions listed below:

1. Since when are you facing this issue?
   
2. Are you aware of any changes being made to the PC?
   
3. Which version of Windows is installed on the PC?

This issue can be caused if a BIOS/firmware update has been pushed to your PC either through Windows Updates or any other OEM media update.



If you have set up the Bitlocker on your PC, I suggest you to look for the recovery key on your Microsoft account. Also, you can refer the article
