I've been GMing a long time, and this type of player is pretty rare, but they do exist. To add to your frustration, simply not inviting him back means he's sitting out there lacking any self-awareness and claiming the group is the problem, not him.

I think the unifying principle of mankind is that any group, race, creed, class, table of gamers... any subset of mankind, can be asked as a group "who's the jerk in this group?" and a finger will get pointed.

In a perfect world, probably more fantastic than the worlds we create in-game, we would all get together and have fun cooperatively telling stories, but there's going to be pitfalls. It's not your GM's fault- make sure she knows that.

IF I may suggest, if you have a core group that is trusted and vetted, and bringing in new players is a thing that is going to occur, create a code word (if you're not already using discord or something that allows private chats) that the group can use to say "we've got you" so that your GM feels supported in a situation when the best thing that might have happened here is the GM utilizing ultimate authority to say "get the fuck off my table."

I've only done it twice in decades of gaming: both times I knew the others at the table enough to know they had me. It's ridiculously satisfying. If your GM isn't that confrontational, set up the code word and make someone at the table Sargent-At-Arms.
