Potential bug: ArcGIS Pro 3.1.3 clears entered parameters from Python Script tool

Has anyone else run into this issue in ArcGIS Pro 3.1+, or was there a change to tbx files in ArcGIS Pro 3.1 that might explain this? We haven't tested in toolboxes created in ArcGIS Pro 3.1+ continue to have the issue- it may be a slight compatibility problem.
