Perform the following steps to make the Reason for Freezing field required during the Frozen transition:

- Click on the Validators link from the panel on the right-hand side.
- Click on Add validator, select the Fields Required validator from the list, and click on Add.
- Select the Reason for Freezing field from Available fields, and click on Add >>. This will add the selected field to the Required fields list, as seen in the next screenshot:
- Click on the Add button to complete the validator setup.
- Click on Publish Draft to apply the change.
