I'm trying to add connectors in Solidworks Simulation, but after entering the connector info, nothing happens when I click the green check to finish the connector. There is no error message or anything like that. Does anyone know how to fix this?

More info: I've tried different types of connectors (link, rigid, and pin) all with the same result (or lack of result). I'm running SW 2023 SP5.0. I've restarted my PC. I've made a new study. I've tried both green checks (top of the feature manager and top/right of the graphics area). When I click on the green check, it puts a little box around it so SW knows I clicked on it. Any thoughts?
