I suspect you need to reinstall this extension [and perhaps some others?]
Extensions don't automatically 'port' over from an earlier version of SketchUp when you install a newer one -
although v2025 does have a new extension to let you do that -
but it's not 100% foolproof, and reinstalling them manually does let you do some tidying up and housekeeping, to keep your extensions 'lean-and-mean'...
