Any luck, I’m breaking on 12.5 too. I simply can’t open the project if I have the plugin included.
EDIT: Nevermind - I was downloading from the wrong place. First I did the git repo direct, then from a link in the forum - but then I found the stable release (for 12.5 anyway):
Also - I had references to ProceduralMeshComponent in my project, which I pulled out. And I updated the Build file to show too.
