I don't know if you still want an anime but I can recommend one anyway
Overlord
It's one of my favorite anime
It is an isekai anime in which the protagonist plays a well-known online game that decides to close its servers, but he decides to stay connected until the moment the servers close, but when the time comes for the servers to close, he does not know disconnect or anything like that, it stays inside the game with no way out.
