Does anybody else have this problem?

So this is more about Rivals in general, and only Widow adjacent, since the last straw happened while I was playing Widow but;

I can't mute people.

Like I can turn off voice chat entirely, but then I'll miss the comments from the few people who actually care and are trying to communicate.

But when I try and mute the person who has their death metal emo ghetto rap blasting at 100% directly beside their mic, I can't find who it is because even muting everybody doesn't turn it off.

Help! I don't know how to fix this!
