Issue with first launching pair (deprecated pydantic?)

[ascamara]

I am running into an issue: I installed pair with pip and there appeared to be no problem. I try to launch (exporting the necessary variables) and then get this error, whether I try to open a pair or with a file. Can you please advise?
