That's easy to say now, but BG3 wasn't getting much attention during it's early access and other CRPGs like the Pathfinder games weren't that popular either. BG3 has been a phenomenon for a multitude of reasons, so saying developers stopped making games like BG3 isn't too precise either. The only game that gets close to BG3 in both features and praise is Divinity: Original Sin 2, which was also made by Larian.
