Adding to some great suggestions ... Sometimes there is no reason to waste time fighting or/and adjusting. Move on and find another team that would appreciate what you have to offer. If you have so much experience you may have a few people to reach out to for connections.

Slowdown and listen. Do you hear this loud sucking sound? It's the demand for software developers. There is a ton of examples in competitive athletics and other areas of human endeavors when someone was unappreciated in one situation and super successful in another.

Still, before you leave, learn as much as you can about the situation, so, if for no other reason, you could recognize it before joining.
