**Your software** My Mautic version is: 4.4.11 My PHP version is: 8.0.30 My Database type and version is: mariadb 10.11.6 **Your problem** My problem is: I cannot update mautic (composer installation from 4.4.11 to 4.4.12 (and up to 5.1.0). These errors are showing: Problem 1 - Root composer.json requires mautic/core-composer-scaffold 4.4.12, found mautic/core-composer-scaffold[dev-RCheesley-patch-1, 3.x-dev, 4.x-dev] but it does not match the constraint. Problem 2 - Root composer.json requires mautic/core-project-message 4.4.12, found mautic/core-project-message[3.x-dev, 4.x-dev] but it does not match the constraint. Steps I have tried to fix the problem: - old composer.json contians: “mautic/core-composer-scaffold”: “4.x-dev”, “mautic/core-lib”: “4.4.11”, “mautic/core-project-message”: “4.x-dev”, - new composer.json (from [https://raw.githubusercontent.com/mautic/recommended-project/4.4.12/composer.json](https://raw.githubusercontent.com/mautic/recommended-project/4.4.12/composer.json)) contains instead: “mautic/core-composer-scaffold”: “4.4.12”, “mautic/core-lib”: “4.4.12”, “mautic/core-project-message”: “4.4.12”, both contain: “minimum-stability”: “dev”, “prefer-stable”: true, Also an composer require xxx:4.4.12 oder composer require xxx:\* does not resolve the issue. Hot to override 4.x-dev with 4.4.12? Thanks
