Colab Notebook suddenly not working. RuntimeError: Your device does not support the current version of Torch/CUDA

I tried deleting everything in my GDrive folder to start fresh and the issue still persists. It was working fine for me a week ago on an A100 session as well as L4, and now the output is feeding me Torch compatibility issues no matter what version or GPU I attempt.

Error below:
