Every time I enter a coordinate in DATA it goes into WASM CRASH!

I just came here to share exactly the same thing. I recently updated to SU4 (MSFS2024). Never had this issue. It happens when I insert the arrival for Tokyo Haneda in my case (RJTT). I do hope a solution is found. I uninstalled and reinstalled (the 350) yet it happened again.

(Oh, this is a 340 forum... well, the same issue applies!)

Hello @LukeSkyBellic @flyalongswithdan

 

I had the same issue with the a340 when doing FRA - SJO. I was about to create a custom waypoint for the ETOPS and when I entered coordinates, red screens occurred. It's really annoying we getting wasm crash at each flight and it's so random. 

Hoping for a quick fix because we can't fly without the stress of having wasm crash.

I want to hope for an update to be released soon

The WASM folder was deleted, I reinstalled it, but... as soon as I enter a coordinate in FIN PAGE, this is the result!

Once again this evening I tried to start a flight, and as soon as I entered the coordinates in the WAYPOINT STORED field, I got the usual WASM crash with the same orange error screens.
At this point I simply can’t fly the A340 anymore, even though I’ve just downloaded the very latest update.
I’ve cleaned out the Community folder and I always delete the wasm folder as well, but nothing changes.

 
Follow that guide to report the wasm crash so they can fix it.
