I'm using Windows Subsystem for Linux (Windows 10, Ubuntu 18.04 LTS). I'll list all the other pertinent versions below.
This setup is working on my Mac machine, without the flags array added to karma.conf.ts as shown below.
So far I've looked at:
Headless Chrome slows tests by 10x
Ubuntu: Cannot start ChromeHeadless
Google Chrome 75.0.3770.80 HEADLESS no longer works inside Docker container
"rebuilding" yarn using npm rebuild --update-binary
Expected Behaviour To launch ChromeHeadless and run the tests
Current Behaviour
Running yarn test as I would normally results in this error:

The command that yarn test runs is ng test --karmaConfig=karma.conf.ts.
Versions
yarn=1.19.0
angular-cli=8.3.2
karma=4.1.0
karma-chrome-launcher=2.2.0
tsc=2.7.2
Edit
Eventually I just gave up on using Linux for this and am using Mac. Watch my issue in the karma-chrome-launcher repo for possible fixes in the future.
