title: Android studio 4.1 is not showing errors into IDE
body: <p>Recently I have updated android studio with Android Studio 4.1, but after updating, the studio isn't showing errors in IDE with red underline or red bar right side. Every time I run the app it throws a single error after compilation. So it's very difficult to say where is the error</p>
  <p>Does anyone have an idea of what to do?</p>
  <p>NOTE: invalidate cache &amp; restart, sync project, clean, rebuild not working</p>
