Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires friendsofsymfony/oauth-server-bundle ^1.6 || >2.0.0-alpha.0 ^2.0@dev -> satisfiable by friendsofsymfony/oauth-server-bundle[1.6.0, ..., 1.7.x-dev, 2.0.x-dev (alias of dev-master)]. - friendsofsymfony/oauth-server-bundle 1.6.x-dev requires symfony/framework-bundle ~2.8|~3.0|^4.0 -> found symfony/framework-bundle[v2.8.0, ..., v2.8.52, v3.0.0, ..., v3.4.47, v4.0.0, ..., v4.4.51] but these were not loaded, likely because it conflicts with another require. - friendsofsymfony/oauth-server-bundle[1.6.0, ..., 1.7.x-dev] require php ^5.5|^7.0 -> your php version (8.2.26) does not satisfy that requirement. - friendsofsymfony/oauth-server-bundle dev-master requires symfony/dependency-injection ^4.4 || ^5.1 -> found symfony/dependency-injection[v4.4.0, ..., v4.4.49, v5.1.0, ..., v5.4.48] but these were not loaded, likely because it conflicts with another require. - friendsofsymfony/oauth-server-bundle 2.0.x-dev is an alias of friendsofsymfony/oauth-server-bundle dev-master and thus requires it to be installed too.
