HTTP/1.1 409 Conflict

I was doing this instructional microgame until it told me to publish the microgame. Now I had no issue navigating to where I publish it directly through the editor, but when I clicked publish, I kept getting this error stating, "Something Went Wrong HTTP/1.1 409 Conflict". I tried to get pass this error multiple times. This even happened to me years ago, I got the same exact error and I was on a different PC. Is this supposed to happen or not and how can I fix it? This is also the final step of the microgame and it says I have to publish it through the editor.,I was doing this instructional microgame until it told me to publish the microgame.
