Failed to read the transcript file:SyntaxError: JSON Parse error: Unexpected identifier "NaN"

[PineapplePTP]

After clicking Autosubs V2 in workspace>scripts the error message: "Failed to read the transcript file:SyntaxError: JSON Parse error: Unexpected identifier "NaN"" pops up. Then I click start process, and the same message "Failed to read the transcript file:SyntaxError: JSON Parse error: Unexpected identifier "NaN"" is displayed again. I've restart davinci, my computer. Was able to get around it by creating a new projecting and starting over.
