This started happening a week ago, and it's absolutely infuriating. It happens with almost anything I download, but sometimes stops if I redownload a few times or change the file data in some way (like renaming). I've had this happen before, but I don't rmember how I fixed it... (Also, my storage is quite empty).
Please let me know if you all need any logs (I don't know what I need to look for). I really just want to be able to save files again.
