Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires nunomaduro/collision 8.4.0 (exact version match: 8.4.0 or 8.4.0.0), found nunomaduro/collision[v8.4.0] but the package is fixed to v6.4.0 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command. Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.

Process completed with exit code 2.
