Installation error with composer: Field 'browser' doesn't contain a valid alias configuration

Make sure you use PHP 8.1 (your log shows 8.3).

Then you have to install all php extensions required for Mautic.

IDK if there is a complete updated list of them somewhere, but install them till you get rid of all errors.

Your log above shows you need to install: php8.1-zip extension
… repeat => get error => install another => repeat
