Security Checkup: “The operation cannot be completed due to insufficient available storage space."

I have been using the Security Center app successfully until yesterday. When I run the Security Checkup I get a popup that says: “The operation cannot be completed due to insufficient available storage space. Go to “Storage & Snapshots” to free up space and retry the operation.” Is there a way to fix this so that I can complete a Security Checkup?
For the moment I have stopped (turned off) Security Center.
Thanks in advance.

If you really want to keep this program have you tried the removal and reinstall of that app? (like advised to in my linked post)
