It works! If you add up FOB and FU and subtract the fuel you put in, it should come to 0. It would be bad if it came to a negative result. I got this info from a German YouTube tutorial by Capt A320

Before I reinstalled the airport, I tried the small program MSFSLayoutgenerator. And it worked. A larger Layout.json was generated than the previous one and that was it.
I found this procedure in another threat in this forum.
The airport looks really sensational.
