Hello,

I am having a reproducible WASM crash when loading the iniBuilds A350-900 in Microsoft Flight Simulator 2020.

The WASM module compiles successfully and is then loaded and initialized, but immediately afterwards I get a c000001d exception during module_init().

The relevant part of the Developer Mode console is:

WASM: Compiled module inibuilds-A350.wasm in 648 seconds
WASM: Module inibuilds-A350.wasm loaded...
WASM: Module inibuilds-A350.wasm initialized.
WASM: Exception c000001d when calling module_init() in module
vfs://inibuilds-aircraft-a350/SimObjects/Airplanes/inibuilds-aircraft-a350-900/panel/inibuilds-A350.wasm

WASM: Module was not ready (in state 5) when trying to load gauge at
m178088ef2d4800fa

This happens every time I try to load the A350-900.

I have already tried the following:

• Completely emptied the Community folder.

• Removed FSLTL and other Community add-ons.

• Completely reinstalled MSFS 2020.

• Reinstalled the iniBuilds A350.

• Let the A350 WASM compilation finish without interrupting it.

• Confirmed that I am using DX11.

The default Boeing 787-10 loads normally, but the A350-900 consistently crashes with the same WASM error.

I also previously experienced a similar state 5 WASM issue with the iniBuilds A320neo.

System specifications

• Aircraft: iniBuilds A350-900

• Simulator: Microsoft Flight Simulator 2020

• MSFS version: 1.39.12.0

• CPU: Intel Core i7-11700

• GPU: NVIDIA GeForce RTX 3070

• RAM: 32 GB

• OS: Windows 11

• GPU driver: 32.0.16.1060

• Graphics API: DX11

I have attached screenshots of the Developer Mode console showing the WASM error.

Could anyone help me identify what could be causing this c000001d exception?

Thank you.
