I've had two crashes in the last 24 Hours. No addon's except WSSS (Orbx) purchased via the in Sim Catalog and FBW A32NX.

Both crashes ex WSSS.

Is there a log to find out what caused the crash? Hoping I might be able to resolve it myself if it's system related vs SIM related.

You could try Event Viewer -> Custom Views -> Administrative Events.

Since yesterday's Sim Update (10 March NZDT), I have had four crashes that rebooted my PC. Flying an A320neo from parked using manual programming of MCDU as well as the MSFS Flight Management system. Only one short flight within New Zealand made it without crashing. The problem often occurs midflight when interacting the the VFR or ATC windows.
