Unreal Engine Issues and Bug Tracker (UE-170907)

Description

Reproduced 3/3 times. Issue also occurs in //UE5/Release-5.0 - CL 20979098 Binary. Confirmed NOT a Regression.

Steps to Reproduce

Create a new C++ Project
Create a new C++ Actor
In the .h file, add the following with the other "#include"s:

#include "UObject/Object.h"
#include "Engine/DataTable.h"

Above the UCLASS definition, paste the following:

USTRUCT(BlueprintType)
struct FTestMemberStruct : public FTableRowBase
{
    GENERATED_BODY()
public:
    UPROPERTY(BlueprintReadWrite, EditAnywhere)
        bool bMyBool;
    UPROPERTY(BlueprintReadWrite, EditAnywhere,
        meta = (EditCondition = "bMyBool==true", EditConditionHides))
        int32 MyInt;
    FTestMemberStruct()
    {
        bMyBool = false;
        MyInt = 0;
    }
};
USTRUCT(BlueprintType)
struct FTestArrayStruct : public FTableRowBase
{
    GENERATED_BODY()
public:
    UPROPERTY(BlueprintReadWrite, EditAnywhere)
        TArray<FTestMemberStruct> TestMemberArray;
    FTestArrayStruct()
    {
        TestMemberArray = TArray<FTestMemberStruct>();
    }
};

Save .h file, and in the Editor click the recompile button (staircase looking button in the bottom right)
Right-Click Content Browser and add Miscellaneous>Data Table
Select "TestArrayStruct", and open new Data Table
Click the "+ Add" button to add a new row
In Row Editor, click the + button to add an array member to your new row
Press the Trash Can to empty array

Actual Result: Crash

Expected Result: No Crash
