Hi iniBuilds team,

I'm writing to report a critical, ongoing issue with the iniBuilds A350 in MSFS 2024 that has made the aircraft completely unusable for me for over four months now.

The problem:
All MFDs crash with a "WASM module crashed" error, every single flight. It happens consistently within the first 10 minutes of the session — sometimes during taxi, sometimes shortly after takeoff — and once it occurs, the entire cockpit is unusable (see attached screenshots).

Error details from the screen:

• Package: inibuilds-aircraft-a350

• Module: /SimObjects/Airplanes/A350/attachments/inibuilds/Function_Interior_A350/panel/inibuilds-A350.wasm

• Gauge: MFD

Topics:

1. The latest update made things worse. Before the most recent patch the crashes were already frequent, but now they are happening even faster and more reliably.

2. This is isolated to the A350. I fly other complex add-ons (including the Fenix A320, PMDG 777) on the same system, on the same flights, with the same scenery and add-on environment and none of them have this issue.

3. It has been more than 4 months. I purchased this aircraft and have not been able to complete a single normal flight in it for that entire period. That's extremely frustrating, especially given how prominently this aircraft is marketed.

Could you please confirm whether this MFD WASM crash is a known issue currently being tracked?

Is there any workaround, beta build, or rollback I can try in the meantime?

If a fix is in progress, do you have any indication of a timeframe?

I really want to enjoy this aircraft — that's why I bought it — but at the moment it is simply not flyable. I would appreciate any response.

Happy to provide MSFS version, system specs, full add-on list, or log files if that helps your team reproduce or diagnose the crash.

What have you tried so far? Reinstall, cleared WASM folders, startign with empty Community folder etc.?

Hi Pilota459

Thanks for jumping in.
Yes, I've already gone through all the usual steps, plus several others I found mentioned across this forum:

• Full reinstall of the A350 (multiple times, both via Content Manager and clean manual install)

• Cleared the WASM cache folders (wasm and wasmFolder under both LocalCache and the rolling cache location for MSFS 2024)

• Started MSFS with a completely empty Community folder only the A350 present, no other add-ons loaded. Crash still happens.

• Rebuilt the rolling cache and disabled it entirely as a separate test

• Verified file integrity through the Content Manager

• Reinstalled Navigraph data and also tested with no Navigraph data at all

• Tested different liveries, including the default one, to rule out a livery-specific issue

• Disabled all developer-mode options and any third-party tools that hook into SimConnect/WASM (FSUIPC, GSX)

• Tried different airports and short flights (including very simple cold & dark starts at default airports). crash still occurs within ~10 minutes

• Updated GPU drivers and verified MSFS 2024 itself is fully up to date

• Reviewed MSFS.log around the time of the crash, the only relevant entries point to the inibuilds-A350.wasm module failing in the MFD gauge

Kind Regards,

Hi, if you're having a crash every time you load the aircraft then it is most likely an issue with the stability of your computer. Have you overclocked your computer at all? Are you running any other addons alongside the simulator? Other users have reported that reducing the speed of their RAM (either turning off EXPO/XMP or reducing the timings of their memory) has had a large effect on the stability of their sim.

In the future, if you have a crash and you please follow the steps outlined here (especially with regards to the logging variables and they help immensely in tracking down the causes of crashes)

The A350 is a complex aircraft and it is asking a lot of the simulator, unfortunately it is simply the nature of the plane that it is sensitive particularly to the stability of the memory on your PC - that said, it is one of the most flown aircraft in the simulator and so we know that it can be stable but there are a lot of variables that are beyond our control.

Hi iniSteven
Thank you for your reply.

I have not made any changes to either the simulator or my computer. There is no overclocking applied, and I am not using any XMP/EXPO or custom RAM settings. My system is a laptop equipped with an Intel i9-13900HX, 64 GB of RAM, and an NVIDIA RTX 4060 Laptop GPU.

The aircraft loads correctly and I am able to start it. However, after approximately 10–15 minutes of operation, I consistently experience a WASM crash.

I will follow the recommended steps, collect the logs and data, and come back with the information to assist with further investigation.

I do appreciate your support.

Kind Regards,
