Hi mao-aavn
It is hard to say what the problem is here.
What does the Details say about this error?
Do you have something in the Error Log? (Search top right or Ctrl+3 -> Error Log)
Or is something in the ivy.log?
Did you try to clean all projects? (Project -> Clean -> All projects)
Maybe there is a problem with the config of this Method Start? Do you have this with every Method Start or only with this one? Can you reproduce this problem?
