Just encountered this erro - any chance of a resolution?

Ok - I fixed this. It always puzzled me why this code failed in 3.12 even though there are tests in the github actons for 3.12.

Removing -qq when install using pip showed that pip downgraded openapi-spec-validateor to 0.6.2 because my virtualenv also installed requests 2.29.0 and they share a common dependency. Upgrading requests module to 2.31.0 fixed the problem - openapi-spec-validator at 0.7.1 does work on 3.12.

This is new behaviour of pip - so I believe. I am only an occasional python develeoper these days and have not kept up.
