Feature File Path and Database File paths not being written after training

Using current version of RVC (pulled the latest to verify just before writing this report),

When Training, it generates the weights but does not generate the feature file or database file required for inference. *** No Index File is created**

I'm using an Ubuntu system, I installed RVC via a venv to ensure no conflicts. This is the tail end of the training excerpt and crash log:
