Mate Reference feature not working in SolidWorks 2025

I recently upgraded from SolidWorks 2021 to SolidWorks 2025 SP5. In 2021, I frequently used the Mate Reference feature to quickly build assemblies where parts are always mated the same way. Since upgrading to 2025, Mate References no longer seem to work. Is anyone else experiencing this in 2025 SP5, and what’s the best way to troubleshoot or resolve it?
