Bug with prompt_toolkit and trace logging. Could only bump up the prompt_toolkit library so much since demos run on Python 3.6. However, I did attempt on 3.9 with the latest version of prompt_toolkit and setting an env var (see prompt-toolkit/python-prompt-toolkit#898). This still did not correct the issue, so reverted to existing code and just handled the exception(s). The output of the trace log is being written to the console, my limited understanding of this would be that the trace log works, but also triggers the prompt_toolkit to do the same work and gets into conflict.
Fixes #2205
