A350 WASM Crash When Entering Arrival&Runway In-flight (but works on ground)

[Bryan.C]

Im experiencing consistant WASM crashs when entering arrival information when aircraft is airborne. When I selected runways and STARs before descent, the system froze instantly. However, the same arrival operations worked perfectly fine when performed on the ground. So currrently, I have to enter my arrival data before takeoff.

-It happens at multipel airports and with different runways and STARs.

-Clearing WASM cache does NOT resolve the issue.

-This issue only occurs when aircraft is airborne, arrival modifications on ground are stable.
