Cannot declare class Liborm85\ComposerVendorCleaner\Plugin

[AbyssMorganCTI]

After install this package i got error every time i call composer require, but works fine after composer update, any idea what happen ?

According to error, composer is trying to load the plugin twice, I don't understand why.

How do you have the plugin installed? global or local? Attach composer.json file. What is the version of composer?

Tested and your use case works for me. I don't know how to simulate it. According to the error, it looks like an bug directly in composer autoloading, when trying to load the library multiple times.
