For anyone facing this issue in Mac OS, make sure that Cassandra version and Java version you're using are compatible. I was using Java 17 and changed it to Java 11 for cassandra 4.0.12

You have 2 issues:

  1. Windows clearly says you to execute powershell Set-ExecutionPolicy Unrestricted to be able to run the startup script
  2. You're using Java 15 that is not supported by Cassandra 3.11 - it works only with Java 8, so you need to downgrade Java

P.S. I would recommend to run Cassandra in Docker on Windows - you'll avoid many problems, as Windows isn't very actively supported platform for Cassandra, and its support could be removed in the future.
