assert theme_name == theme_name.lower()
AssertionError
Couldn't connect to console process.
Process finished with exit code 1
This only happens with version 9.0.0. It works fine with previous versions like 8.31.0.
The reason it failed was the theme_name being NoColor which were not all lower cases. This assertion appears on multiple locations inside the package.
