Hey AzorMachine,
I recommend a few things in this situation:
- Try packaging a clean project to see if you get the same errors. If those plugins aren’t working, it’s possible that you may have removed some necessary files somewhere, or they got corrupted somehow.
- Try reinstalling the engine version that you’re using, or try installing a later version such as the 4.16 Preview and upgrading a copy of the project to that version to see if the same error occurs. If that works, then it’s likely that those files were removed somehow and you’ll need to reinstall the engine.
Let me know the results.
Have a great day
