[2023] Critical Error in Port since 12.6

My first thought would be to disable any Mods you might be running. We had a new Update recently and that can cause weirdness while mods are still being updated.

After that, try a "Check & Repair" in case something in the Update didn't install correctly. If that doesn't resolve it, you might try an Uninstall and Reinstall.

If the issue is deeper than that, CS should be able to help as they have much more technical knowledge than I do~
