I know, you've "SOLVED" the issue by reinstalling. Here are a hint or two for the next time and for the others:
- Yes, the emergency solution, deleting a plug-in code tree, is always available. I haven't come across cases where it causes damages in other areas, other that this "Missing from disk" message in the plug-in report and in case there are other plug-ins dependent on this, they won't function too.
- Specific to H5P there is this confusion of two plug-ins doing the same. Please read H5P Forum - please read this BEFORE posting.
- About "No uninstall" link. Moodle won't offer to uninstall if the plug-in is in use.
