Entire code is highlighted in red

[msrd0]

Description

My entire code is highlighted in red, with error message

No script runtime was found in the classpath: class 'kotlin.script.templates.standard.ScriptTemplateWithArgs' not found. Please add kotlin-script-runtime.jar to the module dependencies.

This might be an error, and it might be worth showing, but this should not underline every single character inside the file with an annoying red line.
