Yes! I am hearing LOTS of reports on this in my comments section! I suggested making a copy of your mods folder, moving the mods folder to the desktop, or disabling it, then clearing the cache and repairing. Then launching the game once to make a new mods folder, checking things work in vanilla, and then moving your old mods contents in to the new :) There seems to be some success with this method.
PLEASE: Make a copy for you Save, Tray, and Mod Folder somewhere safe before doing things, just in case!
I think maybe it has to do with like some history of the mods and how it was interacting before the latest hotfix that is causing the communication error. I don't have a better explanation, and it's likely wrong, but I hope it is fixed soon :)
