My old version of Nik kept crashing my photoshop. They have a half price sale on at the moment (I don't know if it is like DFS and nearly always on). TBH though, I have seen it at full price which is why I kept the ancient free one and not bought it until today. The sale lasts until 29/11/21 supposedly if anyone is interested. It can be activated on 2 machines, so one for me, one for my daughters computer.
