I just installed Magento 2.3 with sample data on an Ubuntu 18 VM.
I'm playing around with creating themes based on tutorials I found online. I created a sample theme, uploaded it, logged into admin, and then switched to it with no issues.

- Go to Menu -> Content -> Configuration
- Click 'Edit' under 'Action' column

How can I fix this?
The URL reporting the 500 error is the following:
