Error message when creating finished file

[cudadotsln]

Whenever I try to upscale a .png it always gives me this error:

Error during FilenamePostprocess():

File name cannot be null.
Parameter name: sourceFileName

Stack Trace:
at System.IO.File.InternalMove(String sourceFileName, String destFileName, Boolean checkHost)
at Cupscale.Main.Upscale.FilenamePostprocess(String file)

I am using a laptop, and I don't have NVIDIA, I am using the PyTorch network.

I too can confirm this problem

Furthermore I get the following assertion error:
"AssertionError: Torch not compiler with CUDA enabled"

Running on a Laptop with a Nvidia RTX 3070ti

Edit, by following https://pytorch.org/get-started/locally/ I've managed to fix the problem
