Why is TestCafe crashing on launch testing Electron app with simple command-line?

I am attempting to run a test on our Electron app using TestCafe. I am getting an error mentioning a "-m" command, however that is not used in my script or command line.

I have everything set up as described here: https://github.com/DevExpress/testcafe-browser-provider-electron#testing-an-executable-electron-application

C:\packages>testcafe -d "electron:C:\Program Files\OurApp\" "C:\Temp\test.js" -hostname localhost

Using locally installed version of TestCafe. ERROR Tested app failed with an error:

Error: Command failed: -m '-m' is not recognized as an internal or external command, operable program or batch file.

Type "testcafe -h" for help.

The script for test.js is below:

import { Selector } from 'testcafe';

fixture `Electron test`
.page('./index.html');

test('smoke 1', async t => {
await t
.debug() 
.click(Selector().withText('Create a new configuration'));
});

What could be the cause?
