removing ghost js-asset in odoo 16

After having removed a js asset file (kanban_controller_zsb.js) from one of my custom module (event_xsb1) in odoo 16 (and moved in another one), it is still remaining and causes trouble to load new js assets of other custom modules to customize a kanban-view.

enter image description here

I have already tried to find this asset manually (in App-Settings > Assets) but i could not find it. I have tried to find the assets.xml of the previous odoo version (v13) in the view but i could not find it neither. So that i am wondering where this js script is located. Any idea how to remove it properly ?
