Yeah, I added a new function to that mod, which this one relied on, but forgot to add that new version as a required dependency, so it wouldn't auto-update the other mod when updating this one (or properly tell the user to download the required version of that mod, if they downloaded it from the website directly).
I actually pulled the original 9.0.11 upload from this mod and re-uploaded it with the corrected dependency, hoping nobody would notice the issue within the two minutes it was up, but you were too quick!
