I don’t know how many times I tried on two accounts to get the most wanted to spawn and got it once on a bad run. A guy on Reddit said 57 times and still not spawning for him. Most of us know where it spawns and that you have to delete it quickly some people still don’t know it spawns on the bottom of the rock room right before crate hallway, and last anchor. Full throttle heavyweight with sword is what I used the one time I found it. When grinding to 550 when salt mine was the first solo op that gave you an extra gear drop option it would spawn around 8-10 runs pretty consistently, but now it doesn’t seem to exist. Somebody posted that if you don’t have side objective finished when you get there it helps it spawn but I haven’t tried that yet.
