Hey @SAproX1, I had a colleague that was running into the same issue with another extension in VSCode. It seemed his solution was by switching to “RobotCode - Robot Framework Support” as his extension and that fixed it from him. If you are already using that extension then I would be sure you don’t have any other robot extensions installed.
And to be clear, while you will get the annoying red underlining, code does execute just fine right?
