Windows Error 0xc00000b0 when requesting /ui

I'm not too sure if this should go here or over to Python-SimConnect, but I'll start here. Once in a while when requesting a variable (in this case here it was FUEL_TOTAL_CAPACITY but I've seen it with other ones) the whole thing just falls apart and delivers a 500:

OSError: [WinError -1073741648] Windows Error 0xc00000b0

I'm wondering if this is something that can be caught here? If so I'd be okay with trying to learn some Python to help. Or would that be an issue for the SimConnect package?
