Debugging a flow allows administrators to test how a flow behaves before activating it or making changes to it. Debugging a flow runs it in real time using test data provided by the administrator or default values from the flow. However, debugging a flow also performs any actions defined in the flow, such as creating, updating, or deleting records. Therefore, if a flow has a delete element that deletes a record based on certain criteria, debugging the flow will delete the test record even if the flow is inactive. References: https://help.
