Not sure why it isn't letting you copy files to your android folder (which shouldn't be a system folder).
Can you try to copy the file from PC to any other folder (maybe the download folder), and then, use an android app (the included "My files", or ES Explorer or any other similar app) to copy the file over to the appropriate Android folder?
I tried using my files. It didn't give me any errors, but nothing was copied to the .Obb folder. I have no idea what's wrong.
