front sprocket nut

Good job that you have changed the nut  :thumbup

Two questions. I see on the pictures the rear wheel is almost at the end of the stretching the chain? Not sure from the picture is that the case.

Do you have enough chain slack, it must be 30-40mm. Do you have measured your chain wear? 10 links must be no more than 150mm long. If it is more the chain has been stretched too far and needs change.

So you were right. 10 links was 200mm long.
I have closely check the chain and was shocked that I didn't see before how worn was it.
All change now. Completly different bike now
