When I attempt to save any place file locally, this message pops up and the place file is gets wiped (0 bytes file size).
I’ve already tried restarting my computer and reinstalling Roblox.
Google drive seems to be the issue. When a place file is saved in a location outside of the google drive folder, I can save the file without any issues.
You can probably restore your file in Google Drive on the web.
(Also, you should edit your title to put the post in Studio bugs, every bug should be in a subcategory.)
I retrieved the temporary file from the location mentioned in the error message. So I didn’t lose any data.
