ok then save the project in gdevelop ctrl+s or save icon and close the gdevelop and make a zip folder of the project that you downloaded because all the changes you made will be saved in the .json file of that folder that you downloaded
yeah that would work check the last updated time for autosave version just hover the mouse cursor over the auto save file and check the time if its near your current time then its ok
just upload as is working or not maybe it will work make a zip of the folder from where you downloaded it whole folder with assets and .json files and upload as source
