Hi @Joshua Kantrowitz
You would probably be better served using IBM SPSS Statistics 29.0.2.0 (20) now that it has been released.
But if your error is truly about licensing, then the first step would be to try to re-license the product. Do this via "Login with IBM ID" (if you are using SPSS Statistics Subscription) or via the License Authorization Wizard (if you have an Authorization code" for the SPSS Statistics on-prem product).
