Were you in combat when you logged in?

Anyway the error is in fact in the add-on called SilverDragon_Overlay (or just SilverDragon) not in Decursive who got wrongly blamed here. I see that you already have created an issue on their Github: https://github.com/kemayo/wow-silverdragon/issues/245

Thanks for the fast response, so Buggrabber made a false accuse.

Yeah happened in combat

it's not buggrabber it's the taint detection system Blizzard put in place to prevent Add-on from making decision instead of the player that made the false accusation. This happens because of shared libraries: SilverDragon probably has a shared library in common with Decusrsive and Decursive's one is the one being used (because it was loaded first or because it's newer) and thus the taint detection system cannot make a correct attribution...
