Can confirm. Yeah, that re-enable trick is solid. Also, double-check if your disk partition style is GPT and not MBR, as that can block it too.

You could also try running the System File Checker tool from an admin command prompt, since that specific error can sometimes point to corrupted system files.

Agreed. I had the same problem. I had to go back into the BIOS and actually enable the TPM security device, not just turn on the setting.
