Intellij is erroring when reading my build.gradle.kts file

Question

The red notification bar at the top says: /org/gradle/tooling/BuildException (java.lang.NoClassDefFoundError: /org/gradle/tooling/BuildException. I can run a gradle refresh successfully, I can run the project successfully, but I cannot get that error to go away. I think my project is actually running fine, intellij just can't properly interpret the build.gradle.kts file for whatever reason. Does anybody know what to do? I included an image. Clicking on the red bar does nothing. I can find no more information about the error message anywhere. I'm running the latest intellij EDU.

Deleting the entire .idea as suggested Luxus would work, but would also be a little bit too extreme.

The problem comes from a misconfigured .idea/workspace.xml, try to find your the part which look like this in the workspace.xml file :

  <component name="StandaloneScriptsStorage">
    <option name="files">
      <set>
        <option value="$PROJECT_DIR$/your_module/build.gradle.kts" />
      </set>
    </option>
  </component>

You'll have to delete the whole <component/> tag, and maybe restart your idea to get rid of the issue.
