Facing"WebDriverException: Timed out waiting for driver server to start"while executing in TestSuite

  1. If we select one or more test case in Test suite for execution
  2. Only first case get passed and the subsequent cases gets failed with below error message. ( on Open Browser test step )

**Kindly suggest , what might be reason behind this…

**Note: If we run the failed test case individually, script run fine without any issue.
Due to this issue I am unable to run multiple test cases in test suite
Error message:
