Simconnect CTD’s MSFS24

ISSUE DESCRIPTION

Description of the issue: If I use 3rd party software which connects to MSFS24 via simconnect then I’ll get a CTD. I’ve tested this with running the following:
Flight Tracker on Stream Deck
SPADnext

If I don’t run any of these applications the sim does not CTD and I can fly for hours. Is simconnect flooding the sim with requests which is causing MSFS24 to CTD.

I’ve done a fresh install of windows 10, only installed required drivers, MSFS24 and the three applications above and will get CTD’s. Remove the software and no more CTD’s. I know it’s not those applications as many people are using them so there has to be an issue with simconnect which doesn’t impact everyone.

[PC Only] Did you remove all your community mods/add-ons? If yes, are you still experiencing the issue? Yes

2 - When loading the sim after programming the EFB step
3 - In flight, can be anytime

Is confirmed by inibuild is WASM Networking and SimConnect cause CTD

Got a link to this at all?

I knew it wasn’t me but it’s taking me ages to get to the root cause of the issue

Got random CTD’s as well. No message, just gone. Happens after about 30-50 mins in flight
