A copy world turned my main world into creative

I’m trying to load into my survival world but I keep getting hit with “there was a problem loading this world” which will be a whole other bug report. I tried to make a copy of the world and I still couldn’t load into it, I put the copy world into creative and it still didn’t do anything, but for some reason it also made my original survival world into a creative world and it says I can no longer get achievements in the world. I know for certain I didn’t accidentally make my original world into a creative world before hand and I refuse to accept that I  just have to start over and make a new world
