UPDATE: It happened to me again, so this is my answer to the most recent poster asking about this:
There was something “stealing” my trace in both cases. With this question here, it was a blueprint with a box trigger I had so I knew when my player was inside or out of a small building so I would change the wind’s audio volume. In case no2, the most recent, it was again a blueprint with a sphere trigger that triggered music whenever I entered it. Make your 3D widget use a new specific trace channel. You are probably using camera or visibility and some trigger box or sphere you are standing inside of is blocking it. So the point chrudimer made is actually what was happening, I was wrong. I WAS inside a trigger. I hope this helps.
