Since the upgrade to the Python LEAN engine, my projects are broken. I get the build error:

"Build Error: File: n/a Line:0 Column:0 - No python module. Ensure there is only one file, named"

The error goes away if I delete every file except for ''.

Screenshot of example project with one extra file with zero code, does not build:

Same project right after deleting the extra file:

Is this how it's meant to behave? Now we have to put all code in '' instead of being able to use imports? If not, what's the fix?
