Shouldn't the lower line "EVENT_MANAGER:RegisterForEvent("ChatRouter"" use your addon's name than instead of ChatRouter again?
Edit:
Please read my comment about your addon's hardcoded library calls from your addon txt file:
https://www.esoui.com/downloads/file...=1975#comments
This did (not your addon so far but others did in the past months) and will break other addons in the future!
Please change this to use the libraries, which provide an own txt file, properly with their txt file, or do not include + add them to ## DependsOn and let users just install it as a standalone version into their AddOns folder.
