Temporary File Lost - SketchUP Free Web

hello. i was working on a project, i havent saved the file and it displays temporary file on the upper left corner of my screen. it crashed and when i came back to it, i was on the home screen where the file was nowhere to be found. it wasnt on my recent files or anything. i also checked on the trimble connect, still nothing.

i need this for a school project and restarting will take a lot of time. i need urgent help please

I wouldn’t expect there to be a file to recover if it had never been saved. At this point I think starting over would be required. Before you get very far save the file with the name of your project so that SketchUp will be able to auto save it periodically. If you have another crash you should then be able to at least go back to the last save.
