[PROBLEM SOLVED] Just got a random black icon appear on the system menu after updating to Luma 5.4 on firm 11. Only appeared after launching Luma 5.4 for the first time. System is N3DS EU. Any ideas what this icon can be? It doesn't boot anything, just loops the 3DS logo. I've seen a few other posts about this random black icons but no one seems to have an answer.
