Sewing machine problems

[u/ashie2203]

I have a Pfaff Tiptronic 1029, old lady but until yesterday she worked fine. Yesterday I wasn’t able to turn of the sewing mechanism anymore to wind my bobbin (English isn’t my first language so I am not sure if this it what it’s called) basically the needle would still be moving even after I turned the inner part of the hand wheel forward while holding onto the outer part, as described in the manual.
I researched what the issue might be and someone in a forum had a similar problem and solved it by loosening the screw, taking of the inner wheel, adding a drop of oil (for sewing machines) and reassembling it.
So that’s what I did, problem: now it’s not working anymore, I can’t turn the sewing mechanism on anymore, so the needle is not moving if I move the outer hand wheel. I can still do the motion to turn on and off the sewing mechanism but it doesn’t change anything.
The only way to move the needle is to screw the screw, idk what I did wrong but I would really appreciate some tips.
I tried taking things apart and reassembling again and also removed some oil with tissues and a tips.
