Error with filesystem

Development Programming & Scripting C++

Hi there!
I have the following code:
TArray ADB_Manager::GetFaultRecords()
{
vector faultRecords;
for (const auto & entry : filesystem::directory_iterator(faultRecordDBPath))
{
string temp = entry.path().filename().string();
temp.erase(temp.end() - 4, temp.end());

	faultRecords.push_back(temp.c_str());
}
for (auto FaultRecord : faultRecords)
{
	FString temp = FaultRecord;
	//UE_LOG(LogTemp, Error, TEXT("%s"), *temp);
}
TArray<FString> result;
for (auto FaultRecord : faultRecords)
{
	result.Add(FaultRecord);
	FaultRecords.Add(FaultRecord);
}
return result;

}

This code is set to be run from blueprints. I can run it when using beginPlay(), however, when I use the function in the constructor script, Unreal crashes. I can’t find the reason why it crashes. Does anybody have an idea? Error:
