Bug [0.4.0-preview] Error: Failed to preload

Confirmed Unity Versions: 2019.1.7f1, 2019.1.12f1, 2019.3.0a10.
Attached is a 2019.1.12f1 project in which the error occurs.

The error gets thrown on startup in both the editor and builds, although the errors in the build are different. Player.log (renamed to .txt) is attached.

Everything works fine with the on demand mode, which is not sufficient due to being too slow.
For simplicity's sake, the locale is set with the specific locale selector in the localization settings.
