All A350 functions unresponsive after clicking "Insert TMPY" in FlightPlan FMS panel

[DiscoStu]

While nearing desintation airport, I selected a runway and approach in the FMS but when I tried to click on "Insert TMPY" button, not only did the FMS freeze but all aircraft functions were unresponsive including all panel visual updates, couldn't lower landing gear, couldn't extend flaps, etc.  I could still move the cursor around the cockpit and the sim continued to run fine.  It was just the aircraft that no longer functioned.

A350-900 on MSFS2020 1.38.2.0

Hi @DiscoStu

Sorry but unfortunately you have experienced a WASM crash.

I have tried a to reproduce your issue but not yet been able to induce a crash by doing the following:

• Trying both Sim Default / Navigraph Navdata
• Swapping secondary flightplans (sim default or navigraph data) into active a few times
• Trying in climb, cruise or descent phases
• Trying to also match what's seen on your FMS as having a DIR TO leg active and then swapping runways.

Regrettably, from our testing so far of reported crashes, very few of them are reliably reproducible as they're very case-specific instances and require close matching of conditions to reproduce. Nonetheless, we are committed to resolve these instances of WASM crashes and improve stability for all. The team is working tirelessly to that end but we also require your help.

In case you experience a WASM crash, please do not close the sim immediately. Use the below guide to properly report the necessary information and reproduction steps.

Thanks!
