Hi,
I am not completely sure if my question belongs here or in "System Administration", mainly because I have no clue what the actual problem is.
I'm currently trying to automatically decrypt my luks2 encrypted root partition during the boot process using the tpm2 chip of my new framework laptop. When trying to set this up with clevis, I used the command from the Wiki but after I entered the luks password it just got stuck and nothing happened (I think I let it run for ~20min). Afterwards I tried running the hello-world example
clevis encrypt tpm2 '{}' <<< 'hello, world' but same problem there. I tried clearing the tpm chip in the bios but that did not help either.
I also looked into the system journal:

Jul 10 15:35:49 jframework kernel: tpm tpm0: tpm_try_transmit: send(): error -62 But to be honest I don't really understand the error messages.
So my main question is: Do you have any idea what could be causing this? I wasn't able to find someone with a similar problem.
