Could you also show the error message text (complete, expand it to show the error message).
I recommand using LibDebugLogger and DebugLogViewer -> Addon settings of DebugLogViewer -> LiBDebugLogger -> Enable stack trace.
It helps showing error message callbacks and watch them later on + creates a SavedVariables file LibDebugLogger.lua which you are able to view / share online here for us:

Share button at the top then to create the link.
Try to use and addon like this here to inspect the global variable RemiCustomAddonIndicator.

You can use /tbug (or /tb) RemiCustomAddonIndicator or /zgoo RemiCustomAddonIndicator to inspect it then.
Is it available after login and player ready (event_player_activated)?
Or does it say in chat: NIL / doesn't zgoo open?
