Unity does not support Ubuntu 22.04+ on 2021.3. In addition, Wayland is not supported.
Reproduction steps:
1. Create a new 3D project
2. Extract the attached “DragAndDropFileinside.zip” somewhere not in the project directory
3. Drag and drop the “dragAndDropThis.fbx” file to the Project View
Expected result: Dropped file is added to the Assets folder
Actual result: Error “ReleaseButton expects buttonId >= 0” or “Assertion failed“ is thrown and file is not added to the Assets folder
