It was indeed File.exist? v File.exists? which had worked side-by-side for decades, but in v2024's Ruby only the former works !
This has affected lots of older or lesser used plugins...
v2.0 is now available in the PluginStore.
The exist? issue was easily done but I also fixed somethings that were archaic in the 13 year old code - like not having its own proper namespace etc.
Its RBZ is also now signed etc.
