Any tips on Studio troubleshooting?

I have a game which I can not publish because of an unknown reason. This problem does not occur with any of my other games. I have it saved on my desktop as a .rblx file, and when I open it I can open scripts and move the camera and it works just fine. It says that it successfully opened the fileI worked on it offline however I do not think that this is the case. Here is a list of thinks I tried to do: > Delete some things because maybe that was what was giving it trouble uploading, however I am thinking about me cutting the update into pieces as this is a very large update since I could not publish it online, and was publishing it on my PC > Saving it to my PC again although that didn't change anything since the file still has the same content > Publishing it a lot but it didn't work. > Anyways I cannot think of any other ways that I can fix this it just crashes when I click "publish to roblox as" if anyone can help and tell my some tips about troubleshooting toolbox studio that'll be great.
