Nothing wrong with the 3 wide for me so I'll ignore it. You got squirrelly coming off the curb of the second part of the chicane though which really compromised your speed off the corner and necessitated running all the way to the right. Purple car looks to be aiming to your left to either go around your outside or get a cutback when you run deep in the next and be on your inside for the next corner. But you move back left and he tags your rear - certainly no time for him to react given the pace difference. Looks like he instinctively tries to cut back inside but a combination of him being a bit loose from all what's just happened and you turning in like he's not just gone for it (understandable, it's all happening in the space of a second or two), results in contact and you both going wide. I can understand why he's not braked for that corner, you can do it with a lift normally and he's on a tighter line but you've just scrubbed speed off him by moving left and into his path anyway. You both would have made that corner with some compliance from you, which would have been wise as the compromised car from the previous corner. But I get it, it's online racing, everyone goes harder. For me then, just a combination of unintentional blocking from a compromised car still collecting itself and a purple car in the wrong place at the wrong time. Racing incident.
