Katalon Recorder Command line Runner

When using the command line runner in Ubuntu on firefox the Tests are not executed most of the times. First firefox is started and “Sign up | Katalon Solution is opened, no second window is opened after this and the commands arent executed. In the logs only “[INFO] Message: listening on *:3500” is shown and after a while Firefox crashes.
Could anyone please help me with this?

Hi there,

Apologies for the late reply. Were you able to solve the problem? If not, could you provide a screen recording so we could see where the problem lies?
