He wanted out for a long time, IIRC as early as MGS 2. 4 was originally planned to end with Snake and Otacon being captured and executed for terrorism to put the final nail in the franchise’s coffin, with Kojima only dropping the idea after his entire writing staff protested.
I think you hit the nail on the head with his dissatisfaction being why 5 felt so different. It barely feels like a Metal Gear game even if the stealth is at its all-time best, but you can definitely see some proto-Death Stranding DNA in it in retrospect. He was clearly experimenting with new gameplay ideas, which might explain why the game went so far over budget and ended up unfinished.
