upload LP project not working when labeling on windows but uploading on linux

[Xiaoyun-Sherry-Li]

I'm using Lightning Pose in windows system locally via WSL. For my project, I created a new lightning pose project on the pose app by uploading my labelled frames, which are arranged in lightning pose context model format.
Lightning Pose is able to create a project based on my input data. However, when I move to the next stage, where I try to use my labelled frames to train a model, it seems that LP does not recognise my labelled frames properly (see pic 1), since it shows that 0 of all my frames are labelled.

So to go a step back and check, I went to the Label Frames tab and try to visualise my images in the label studio. But I could not log into label studio - no responds is generated when I clicked on the "log in" button, with some errors displayed at the backend. (see pic 2). I also tried opening label studio using the LP online studio version but fail. It seems that the fact that my data was generated in a windows file format is (at least partially) contributing to LP failing to recognise the file in both the online and WSL installation.
