Lua error popping up on load with an unknown event "CURSOR_UPDATE". The error seems to mention other addons as well if they are enabled at the same time as GatherMate2. If you disable GatherMate2, no more lua errors. Here is what I believe to be a "pure" error message:

Here, as an example, is how it looks if the addon "ArkInventory" is also enabled.

Since all lua errors stop when GatherMate2 is unloaded, I believe this is an issue with GatherMate2.

I get the same errors under the same conditions.  I can't imagine how the two addon's paths cross tho except that they both use AceEvent-3.0.

I got same issue

LE : What I did was clear variables, delete addon manually and reinstalled. Now it's working fine.
