BitLocker error

Question

Hi,

I have a user that's unable to use BitLocker to encrypt his drive. Whenever he runs BitLocker, he gets a message saying "The handle is invalid". Not sure what this means, I had the user go into the BIOS and clear the TPM chip, but that did not resolve the issue. Any help would be great.

Laptop: HP EliteBook x360 1030 G3

Intel Core i7-8650U @ 1.90GHz 100
15GB RAM

Thanks,

Usually, users get ‘the handle is invalid’ error on the Windows login screen or or running a script.
What your user have done on this PC? Did he ever used BitLocker, did he run manage-bde command to enable BitLocker?

Try the following methods to see if can fix issue:

1. Update system to the latest build, check for updates in Settings.
2. Changing LocalAccountTokenFilterPolicy Registry Key
   Press Windows + S, type “command prompt” in the dialogue box, right-click on the application and select Run as administrator.
   Once in the command prompt, run the following code:
   reg add HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\system /v LocalAccountTokenFilterPolicy /t REG_DWORD /d 1 /f
   Restart the computer and try to enable BitLocker from control panel.
3. Use the System File Checker tool to repair missing or corrupted system files
