Problems using TPM to decrypt LUKS after install with archinstall

Hi all, I installed arch from archinstall and enabled encryption with the installer. I decided I want to unlock the device using the TPM but there is a problem, I followed the guide on the wiki that talked about the TPM and related pages but there is a problem: the laptop on startup is waiting endlessly to decrypt and no longer boots.
I don't know how to provide the logs because I can't log into the system when this happens.
Could you give me some advice on how to solve this problem?
I spent quite some time trying to resolve this.
Thank you very much and have a nice day/evening

Re: Problems using TPM to decrypt LUKS after install with archinstall

You can boot the iso via USB and see if you can attach/unlock the system-root manually. If that works, add a second normal LUKS password/key for the device and test that one works before you try to re-run anything tpm related, or undo it by regenerating the initramfs without tpm enroll and related.
