no, the source folder is in the project root. if it is a blueprint only project, you don’t have one (its c++ files). I know it is cumbersome, but this is the only way I’ve recovered all my projects. it happened to me quite a lot. start using SCM like git or svn - this will save you in the future as you can go just back to a revision which works. maybe start with deleting/renaming the Config folder and try to open it. then continue with assets in Content/ - and remember the backup
