I am using ELVUI, but have used it in the past without issues until recently. Have uninstalled and re installed to no avail.

I am also using ElvUI, but I am using Bazooka to remove the mini map button and put them there. If this can help you, use it.

Sadly, I can’t fix anything now as I don’t play anymore to WoW…

Yet, maybe I can help you try to fix it yourself:
Did you try to run alone Rotation Builder to check if the error was still there?
