Hey there forum!
I’ve been experiencing some strangeness with my personal project lately, I updated it from 4.22 to 4.24 and the game has now started experiencing what seemed like random crashes.
The game is a point and click style game so some of my blueprint code is dependent on the current screensize to do things like move cursors around and what not, and I noticed that the crashing is only happening when I play in editor after having pressed F11 to go fullscreen.
Playing in standalone also crashes, playing in a separate editor window also crashes, these two crash no matter if you’re in fullscreen or not.
It only crashes when I’m using my 2D point and click style pawn, pawns that do not use that code do not crash.
The 2D point and click style pawn uses the blueprint function “Get Viewport Size” in order to move the cursor around and such, I was wondering if this could perhaps be the issue?
Now when the engine crashes it does not go to the usual crash logger but rather just dies straight out, I do get some logs however and I found this in the log.

Anyone out there got a clue what could possibly be causing this? I’ve never experienced this on previous versions of the engine.
