I don’t know if there is any add-on that requires a stand-alone WASM module that is sold on the MS Marketplace so, instead of the Community folder, it would be located in the Official folder.
Probably not, but it won’t hurt searching there too. If you don’t find any modules, than it simply means that in YOUR case, the CTD on start is not caused by a stand-alone WASM module, but something else entirely.
A stand-alone WASM module active will surely crash the sim, 100% of the time, but that doesn’t automatically means every possible crash is caused by that.
