Those kind of errors happen when trying to run a symfony/translation version that is not compatible with your PHP version (for example when running composer install with PHP 7.3 then running your app with PHP 7.1).

Your code is not enough to reproduce the bug (it works on a standard installation) and equivalent code also work in the Carbon live editor:
https://try-carbon.herokuapp.com/?embed&input=Carbon%3A%3AsetLocale(%27nl%27)%3B%0D%0A%0D%0Aecho%20Carbon%3A%3Anow()-%3EtranslatedFormat(%27l%20j%20F%20Y%20H%3Ai%3As%27)%3B%20%2F%2F%20zondag%2028%20april%202013%2021%3A58%3A16%0D%0A%0D%0Aecho%20%22%5Cn%22%3B%0D%0A%0D%0Aecho%20Carbon%3A%3Aparse(%27-1%20day%27)-%3EdiffForHumans()%3B%20%2F%2F%201%20dag%20geleden%0D%0A

Please provide your composer.json and check installed versions of jenssegers/date, nesbot/carbon and symfony/translation then check the PHP version you use for install composer dependencies and the one you run on the machine that gives this error.

In the development machine i have php 7.2 and install the composer with args --no-interaction --ignore-platform-reqs , in the production machine i have php 7.3.10 and return this errors

Did you clean all you caches (like OPCache, APC, etc.) that may keep some obsolete PHP files as precompiled?

I have the same issue, it appeared when upgrading to version 4. Locally using Laravel Valet it works just fine, the issue is on my production server, both local and in production running php 7.3. No idea of what could be happening!
