Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires academy/academy-custom-css * -> satisfiable by academy/academy-custom-css[1.0.0]. - academy/academy-custom-css 1.0.0 requires shopware/core ~6.6.0 -> found shopware/core[v6.6.0.0, ..., v6.6.9.0] but these were not loaded, likely because it conflicts with another require.

Process completed with exit code 2.
