The .sln and .csproj files won't help. You need to upload everything that is in the Build folder when you build the game. You might have named the folder something else. But you need to include all the files that are generated when you build the game. Let us know if you upload the full build and I'd be happy to give it a try!
It looks like you uploaded the entire Unity project folder, but I don't see a Build folder in there. You need to build the game in the Unity Editor. It will prompt you to either select a folder or create a new one. You need to upload all of the files it creates in that folder, and only those files. Here's the page about creating builds from the official documentation: https://docs.unity3d.com/Manual/PublishingBuilds.html
There are also lots of tutorials out there if you search around. Best of luck!
