Both the OP and the article are both about a Reddit post by one user who got a weird error when trying to run both games at the same time.

There’s nothing presented, in either article, that suggests that it is a widespread problem.

Just because the clickbait press is reporting the same story with different headlines doesn’t mean it is a widespread problem. They’re both writing about the same Reddit post and the same X reply.

It’s a non story
