Doesn't work any more - throws NoClassDefFoundError error

[David-Hari]

I have been using this for a while now and I can't live without it. However, when I opened up my IDE today I found that the "Project" tree no longer loads any files under each project and the IDE reports the following error:

I'm using IntelliJ IDEA 2024.2.4 (Ultimate Edition), Build #IU-242.23726.103.
I don't remember it being broken after upgrading to that version of IDEA, so it's either been broken by a minor update or it's something else entirely. I did a full Repair IDE, Invalidate Caches, etc before figuring out it was this plugin that was causing the folder tree to not show.
