Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires medicalmundi/oe-module-npi-registry * -> satisfiable by medicalmundi/oe-module-npi-registry[0.0.1, ..., v0.1.0]. - symfony/event-dispatcher is locked to version v6.4.8 and an update of this package was not requested. - medicalmundi/oe-module-npi-registry 0.0.1 conflicts with symfony/event-dispatcher ^6. - medicalmundi/oe-module-npi-registry[v0.0.2, ..., v0.1.0] require symfony/event-dispatcher ^5.4 -> found symfony/event-dispatcher[v5.4.0, ..., v5.4.45] but it conflicts with your root composer.json require (6.4.8). Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
