Importing flight plan to MSFS24 makes the SIM unable to load / shutdown

I created a flight plan in SIM brief. Once I go into free flight and set up my departure airport, I then press tab and import the flight plan to the SIM so that I can fly IFR and the ATC recognises the flight plan. At this point, I try to continue, but the SIM goes into a seemingly infinite loop state. I tried also not importing the flight plan before I am in the cockpit. This allows me to use the flight plan as normal, but upon exiting MSFS24, the SIM does not shutdown and I have to force a shutdown using the Task Manager.
