IniJamir Posted January 27 Posted January 27 Inibuilds A350 Master WASM Crash Thread v1.2.4 FS2024 This thread will be the new location for all WASM Crashes relating to the Inibuilds A350-900/1000 for Microsoft Flight Simulator 2024 Below this message will be where users can upload their WASM Crashes pertaining to the current version of the A350. NOTES: If you do not see orange expectations screens on your displays or "WASM exception in X gauge" in the developer console it is not a WASM crash. The "sim-freeze" is a separate event that is tied to something on the server side which we are investigating with Asobo. All WASM Crashes existing in this thread will be removed following the release of a new update. i.e. Any Crashes identified in Inibuilds A350 v1.2.4 will be removed from the post following the release of v1.x.x and so forth. Please ensure that when posting WASM crashes you post the WASM log from the in-game console alongside any media (photo/video) and a brief description of what you were doing leading up to the crash. Instructions on what to do are located in this thread - Any posts not following this format are subject to deletion. Thank you

packman2002 Posted March 19 Posted March 19 by the way, did shutdown msfs2024, re-opened, started aircraft with engines running on the runway. loaded autosave status, a bit earlier on the flight. did proceeed farer into the destination. enterred STAR, Runway, via and transitioni. was fine this time previously i put via as last item (selected none and crash happened. no idea if relataed to entering the arrival data late or the order enteirng the arrival date.
CaptainSlow747 Posted March 19 Posted March 19 I was just setting up a flight and had a WASM crash when I clicked on ATC COM, prior to that I entered 4 Fixes in the FIX page.

MD82 Posted March 19 Posted March 19 Sorry if I did not post as stated above. So, it might be of little help. I came here to this site afterwards: Flight TPE-LHR WASM #1 was when entering arrival STAR during ground preparation on active F-PLN Flight Restart WASM #2 was when entering destination (RCTP) into SEC 2 to build a quick return

QY_Nebula Posted March 22 Posted March 22 Flight ZSPD-RCTP. This happened far away from Top of Descend point. I was selecting Arrival procedures.

Out of approximately 10 flights, 6 resulted in a WASM crash, making the aircraft unreliable to operate. This significantly degrades the experience. At this stage, flying the A350 feels unstable and unpredictable, as crashes occur regularly without a single consistent trigger. Because of this, I am currently reconsidering using this aircraft, as most flights do not complete successfully. Attached, you will find a compressed file containing the requested files. If you require any further information, please do not hesitate to ask. Reproducible Scenario (Confirmed) Taxi after landing (reproduced twice) Normal landing Vacating the runway Taxiing after runway exit → WASM crash occurs This scenario has been reproduced 2 times under similar conditions. Other Observed Scenarios FMS / Approach Entry (3 occurrences) While entering approach procedures in the FMS Example: Seoul → Tokyo (OFP available) → WASM crash At Gate During IRS alignment → WASM crash In-flight Failures Sudden loss of navigation Full WASM failure without orange screen indication Reproducibility Summary Approx. 60% crash rate Occurs across: Taxi phase FMS programming Gate operations In-flight Not route-specific Additional Files Available Console screenshots WASM error screenshots OFP (PDF) Autosave (.bin prior to crash) Impact These repeated WASM crashes severely impact usability and prevent normal operation of the aircraft. At the moment, the experience is highly inconsistent and unreliable, making it difficult to complete flights. Final Notes Given the frequency and variety of triggers, this appears to be a broader stability issue rather than a single isolated bug. I am happy to provide additional logs, files, or test scenarios if needed. WASM.7z
Papy59 Posted March 29 Posted March 29 After 2 hours of flight, the aircraft's controls are completely frozen, but it continues to fly off course without any possibility of regaining control. - Aircraft: A350-900 - Flight: KMIA - LFPG - Nvidia 3060 TX - AMD Ryzen 5 5600 6-Core Processor 3.5 GHz - MSF2024 internal graphics settings are, for the most part, set to "medium".

Flight was into EDDM if it matters, I was still on the GND at Denver though.
Silent Shark Posted 19 hours ago Posted 19 hours ago (edited) Another crash to report. Been having a lot more recently, seems to be getting worse with these recent releases. Hardly had any before, hope you can figure them out. Flying KDTW to KMIA. I'd selected the approach runway and STAR already, but was using SayIntentions, and saw that a transition was included so wanted to set this. I find almost all of my WASM crashes happen in this scenario, changing the already selected approach. Rarely does it crash on the initial selection. My workaround has usually been to do the selection 'from scratch', as in pick the runway again, pick ILS, pick the STAR and then pick the additional bits. But no good here, still crashed it.

Kirkus Posted 2 hours ago Posted 2 hours ago After the 2nd Ghost WASM I turned off any2GSX in the task manager and was able to land at ZSPD 6h and 37 mins later with out an issue, I might try my next flight with out it running in the background. When I put the info in to Chat GPT, it indicated that there was likley a simconnect overload, causing a disconnect. html_ui/global/undefined → UI lost backend feed SimPropContainer errors → sim no longer recognises aircraft systems Script failures → cascading after disconnect
