The issue is being caused by an environment variable that has newline characters in its value. I’ll update the parsing to be more robust.

@markmcv, in your environment variables (listed from the printenv bash command) you have a variable that is actually a function, BASH_FUNC_which%%. How is this defined in your bash startup scripts?
