Why does my computer keep asking for BitLocker key?

Could you elaborate on the specific scenario where your computer keeps prompting for a BitLocker key? Have you recently made any changes to your system, such as updates, hardware upgrades, or significant software installations? Are you the only user of the computer, or does it belong to a corporate network where BitLocker encryption may be enforced? Understanding these details will help in pinpointing the potential reasons behind the repeated requests for the BitLocker key. Additionally, is there any error message accompanying the prompt? This could provide further clues to resolve the issue.
