…, v14.14.0, v15.0.0, …, v15.3.2].

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 laravel/cashier:*” to figure out if any version is installable, or “composer require laravel/cashier:^2.1” if you know which you need.

Any idea to solve it? thanks

Im expecting i install it without –with-all-dependencies
