Problem with APU in A320 FBW stable version

After last update Windows 10, I have problem with APU master switch (fault) in A320 FBW stable version

The 4 time I try going out MSFS, the problem is resolved.

The last time I had that button light up in the APU, is because my fuel tank is empty.
I had to refill the tank, turn off APU, external power, and battery. Then turn on Battery and external power again, and the APU will start as normal.

Thank you; I´ll keep it in mind for the next time.

I am stuck. The light that is shown comes on when I press APU start. The fuel Tak is full. I also have problems with the battery switches. They will not come on until I start Ext Power. I have the same problem with all versions on FBW A320. If I press “Control E” the engines will start and the APU comes on then.
