Sorry, got caught up with life. Updated to latest Forge 1.14 version (28.0.45), but same crash problem.
Crash report: https://pastebin.com/eG4X8xJG
Debug.log: https://pastebin.com/567UiKL2
For those mods then I have to go to the mod authors, yes? If so then that would be a separate issue from this crash I'm experiencing and that part at least can be disregarded here.
