Every time I’m recording steps, if I have a Close Browser step and remove that step; then try to rerun the steps it gives me the following error:

It won’t go away until I close out the recorder and restart my step recording.

I open Katalon Studio, create a new test case, open the web recorder, record some steps, then hit the stop button which adds a ‘Close Browser’ step to the end of my case. I then remove that last step while still in the web recorder and attempt to run the steps from the recorder, and the error in the original post spawns and nothing happens.
