help!

Im not sure where to post this. Im a new comer to the forums, I never really had to use forums before but in this situation I need some help. I lost all my data in forza horizon 4. Ive been playing this game on PC for several months and I always had to disable my antivirus to get the game to work. for about a month I could not get this game to work on my PC for nothing… I even tried running it on my laptop and the same thing would happen… it would crash back to desktop right after the sena intro scene, I reset the app and all that jazz and nothing worked. after countless times trying to conntact microsoft and or turn 10 studios I got no feed back… so one day after this lego thing I decided to try and reset the game again… and bam. it worked, but when I logged in I statred from the very begining…I was dumbfounded…I was totally lost after that… ok so I played a little bit and thought maybe it was a glitch. I did this one danger sing set a new PB and I seen my name in the list set in the mosler… so how can my name show up in the list if im all ready in the game playing it…it like im there but not there… what the heck is going on?? can anyone help? is this game not saved online so you dont lose your information or is it stored on your PC … if it is I couldnt find it… any help is greatly appreciated.
