I updated my Intellij IDE to:
IntelliJ IDEA 2021.1 (Ultimate Edition) Build #IU-211.6693.111, built on April 6, 2021

Error: Could not find or load main class com.intellij.rt.junit.JUnitStarter

Error: Could not find or load main class com.intellij.rt.junit.JUnitStarter
These are some configs of my IDE:
