That is an error when files cannot be found. Please try download the zip file and extract it again and see if it's fixed.
It happens even if I just download the demo with the itch downloader and apply the new plugin separately.more importantly, is it referring to this file: $Template_Idle_f8? because it is in the folder.
Do you mean you copy the plugins to a new project and it gave that error?
Also please visit the Discord server and give me a message so I can support you in real time. Replying on itch is quite slow.
