struct.error: unpack requires a buffer of 4 bytes (error running example data sets on Windows)

Hi, finally managed to install Gsplat on my Win 11 (RTX3090) machine without issues using CUDA 12.4, but am running into problems running the simple_trainer.py file. Am getting the following error when trying to run the example data sets:
