This happened to me too. After enabling TPM, I also had to switch my disk from MBR to GPT before the installer would finally work.

Did you also check if Secure Boot is enabled in your BIOS? Hope that helps.

You could also try enabling TPM 2.0 in the BIOS, as that's a common requirement people miss. Good luck!

Another option is to check if Secure Boot is enabled in your BIOS, since Windows 11 needs that too.
