Problem 1
- Root composer.json requires nunomaduro/phpinsights * -> satisfiable by nunomaduro/phpinsights[dev-a0e696746c60cf67123428b97f98acec76f3cde0].
- nunomaduro/phpinsights dev-a0e696746c60cf67123428b97f98acec76f3cde0 requires symfony/cache ^4.4|^5.0|^6.0 -> found symfony/cache[v4.4.0-BETA1, ..., 4.4.x-dev, v5.0.0-BETA1, ..., 5.4.x-dev, v6.0.0-BETA1, ..., 6.4.x-dev] but these were not loaded, likely because it conflicts with another require.
