We have recently updated our RJ Professional - MSFS 2024 Known Issues FAQ to provide clearer instructions on how to ensure the WASM gauges compile correctly on the first load.
For any users experiencing issues with the RJ loading into a flight with engines shutting down, the IRS not aligned, or just generally in an incorrect state, please have a read of the steps listed in point 1 of the above FAQ and that should get you up and running.
