Disabling Avionics due to low memory resources

Evening all,

Flying MSFS 2024 on the Xbox Series S, attempted to do Dublin - Frankfurt and about 25 minutes into the flight, all my avionics got disabled with the warning message "Disabling avionics due to low memory resources, other settings may be disabled" is there a way around this, a way to fix it? What can I do, really unsure and if I am unable to fix this I won't be able to do longer flights.

Thanks
