After the new levels had been added I got a crash anytime I ran it that said that the GPU crashes (shown below). When starting Unreal I had gotten messages about how the NVIDIA driver needed to be updated with Unreal 5, but it had been working fine. When more models and objects were added it finally decided to affect the development process and crash.

The warning that it gave me was for the driver that I had installed already. It was saying that with the version of the NVIDIA driver I had has known issues in d3d12 but it didn't cause any issue up to that point. I had to re-install the game ready drive using GeForce. After this I had to restart Unreal and the game ran fine with no crashes or warnings.
