about Movie Render Queue runtime on ue5.2

Currently, after rendering with levelsequence and mqr, when I load pak models in the scene, there is a loading error.I use pakLoader plugin.
bool FPakLoader::MountPakFile(const FString &PakFilename, int32 PakOrder, const FString &MountPath)
{
if (PakOrder == INDEX_NONE)
{
PakOrder = GetPakOrderFromPakFilename(PakFilename);
}

bool bResult = false;
if (MountPath.Len() > 0)
{
	bResult = GetPakPlatformFile()->Mount(*PakFilename, PakOrder, *MountPath);
}
else
{
	
	// NULL will make the mount to use the pak's mount point
	bResult = GetPakPlatformFile()->Mount(*PakFilename, PakOrder, NULL);
}
return bResult;

}
