After copying project to new folder, open folder and save as workspace, error:
This setting cannot be applied now. It will be applied when you open this folder directly.
Applies to:L

{
    "files.associations": {
        "*.inc": "pascal"
    }

Workaround: do not save as workspace, always open folder directly
