Permission denied error on windows

[Dennis182]

I am currently using Labelme for a research project. The experts for the labeling had a problem with permissions under Windows. Apparently everything worked great the first time. Now the predictions can no longer be opened directly via the json files (PermissionError: [Errno 13] Permission denied: path). But via open dir the jsons can be opened without problems. Since this worked for a while, I think it is a Windows problem. Is there anything known about this?

By the way, thank you for providing this great package
