i have meet the same problem and finally fix it.
the problem is something incompatible with pytorh_lightning on windows
i have goto the original instant-nsr-pl github repository and found there exist some issues with similar problem , and the author has publish a branch named "fix-win-data" for these problem , then i compare the changes form:

bennyguo/instant-nsr-pl@main...fix-data-win

and then i remove all ".to(self.rank)" and "device=self.dataset.all_images.device" from the code, and add ".to(self.device)" to the data that need to send to gpu.

and final , it work
