How should I even debug this crash

Update for anyone else with this problem,
this code was the issue:

FNPCHitInformation newInfo;

newInfo.hitTimer = 2.0f; 
newInfo.player = hitPlayer;

recentlyHitNPCs.Add(newInfo);

It seems like the crash occurs randomly when adding an element to a TArray of custom UStructs.

The solution for me was to remove the UPROPERTY() tag from the TArray in the header file.

//UPROPERTY(BlueprintReadWrite)
TArray<FNPCHitInformation> recentlyHitNPCs;

Removing the tag is not ideal but it works for me so whatever.

As Auran13 said it might be a garbage collection problem, I think It’s probably an unreal engine bug.
