[OPENING PROJECT] MAJOR ISSUE

Summary

After changing my verse code by adding a few new functions and variables, I saved and tried to build my verse file but UEFN crashed with this crash report:

Unhandled Exception: EXCEPTION_ACCESS_VIOLATION writing address 0x0000000200000009

I am no longer able to open my project as UEFN crashes while loading the project. This only happens in this project.

Stability

Steps to Reproduce

I’m not totally sure whats causing the crashes but I do think it has something to do with the loops in my functions.

  1. Add functions that have parameters that take in an agent, then call another function that also takes in a agent and start a loop:

    PlayerEnterStorm(Player:agent):void =
    playersTeam := GetPlayersTeam(Player)
    if(playersTeam = 1 or playersTeam = 2):
    set playersInStorm = playersInStorm + array{Player}
    spawn:
    StormDamage(Player)

    PlayerExitStorm(Player:agent):void =
    Print(“Player exited storm”)

     index := GetIndex(playersInStorm, Player)
     if(newPlayersInStorm := playersInStorm.RemoveElement[index]):
         set playersInStorm = newPlayersInStorm
    

    StormDamage(Player:agent):void =
    stormDamage := 10.0
    loop:.
    Sleep(1.0)
    if (FortCharacter := Player.GetFortCharacter):
    FortCharacter.Damage(stormDamage)
    index := GetIndex(playersInStorm, Player)
    if(index = -1):
    break

  2. Save and build the verse file.

  3. UEFN crashes.

Expected Result

The code builds and UEFN doesn’t crash.

Observed Result

UEFN crashes with with this crash report:

Unhandled Exception: EXCEPTION_ACCESS_VIOLATION writing address 0x0000000200000009

Platform(s)

UEFN

Additional Notes

There were no errors visible in the compiler.

Think i’m having a similar issue which is causing UEFN to not open at all…
For me this is now like the 12th UEFN update in a row where there is some sort of crash issue from letting me use UEFN on a stable connection without any problems…
