As mentioned in #26598 (#26598 (comment)), you should be able to fix this by using node version 12.9.1 or earlier.

Thank you for your report. We fixed this just now with the release of Metro 0.56.4 and 0.57.0. Update your packages and re-create your project and things should work for you again :) Sorry for the inconvenience.
