Halo has been struggling for decades. Not dying, but certainly struggling. And one of the clear reasons for the franchise's fall off since Halo 3 is that Xbox has been losing the console war.

Microsoft revealed that “multiple” Halo games are currently being developed on Unreal Engine 5 with 343 Industries having been renamed Halo Studios and shelving its own Slipspace Engine in favor of Epic Games’ product.
