Indeed, PHP CS Fixer is not yet compatible with PHP 7.3,
as each minor release of PHP introduces changes in syntax, for regular users it's a new feature, yet for us, who operates on low-level of tokenization, this is BC breaker, and without adjusting the project it will crash on trying to fix 7.3 code.

I'm also closing this one as duplicate of it.

You can still enforce composer to install PHP CS Fixer on PHP 7.3 anyway with --ignore-platform-reqs.
Then, you can set up PHP_CS_FIXER_IGNORE_ENV env var to enforce PHP CS Fixer to run under PHP 7.3, but you may experience unexpected issues.
