I cannot load any different airport and plane - always the same airport and same aircraft - non ascii windows 10 account name

Hi, firstly thanks for helping us out, but I created a batch file, launched it before starting the sim, it doesn’t seem to help, unfortunately. Also this seems like a serious issue, I just wanted to know, why might have this happened all of a sudden of one’s sim, like I load in at any airport, close the sim, then when I load in the next time it just keeps loading at the same previous airport?
