Upgrading Crossplane hit a crash loop in the core pod with crossplane: error: cannot initialize core: cannot apply crd: cannot patch object ... status.storedVersions: Invalid value: must appear in spec.versions. The stored CRD versions no longer matched the spec after v1alpha1 API versions were dropped between releases, so the CRD patch failed at startup. One reporter hit it going from 1.12 to 1.13.
