I'm running macOS 13 public beta on an M1 Mac Mini on a fresh partition. I opened safari and went to twitch.tv. Not 5 seconds later, "Safari is not responding".
I reported the bug. Not sure what else to do now except yell at clouds, I guess. Anybody else running the beta, please report this if you can reproduce. I'm gonna go and have a drink. Here's hoping my Logic Pro test later today is a little more successful.
