When Python is executed in an empty environement, not only it displays "Fatal Python error: Failed to initialize Windows random API (CryptoGen)", but it opens also the fatal error popup on Windows.

The issue #19983 proposes a patch to not abort() at exit, but exit with an non-zero exit code instead. The same should be done for this error.

By the way, we can maybe help the use to fix this issue with a better error message. For example, add in the message " (check if SYSTEMROOT environment variable is correctly set)", maybe only if the environment variable is not set.
