Can't install plugin

[maxpdesign]

When I try to install the plugin I get the following error:

Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Root composer.json requires born05/craft-commerce-buckaroo ^1.3 -> satisfiable by born05/craft-commerce-buckaroo[1.3.0].
    - born05/craft-commerce-buckaroo 1.3.0 requires craftcms/commerce-omnipay ^2.0.0 -> found craftcms/commerce-omnipay[2.0.0, ..., 2.1.1] but the package is fixed to 3.0.3.1 (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.
You can also try re-running composer require with an explicit version constraint, e.g. "composer require born05/craft-commerce-buckaroo:*" to figure out if any version is installable, or "composer require born05/craft-commerce-buckaroo:^2.1" if you know which you need.

Installation failed, reverting ./composer.json and ./composer.lock to their original content.

Th plugin that requires craftcms/commerce-omnipay:3.0.3.1 is craftcms/commerce-mollie. But when I uninstall that plugin I get the following error:

Any idea how to fix this? Currently told the client to use Mollie instead of Buckaroo
