When I tried opening a saved project from PyCharm, it pulled up the project, but the interpreter was not listed as a run option in the top right hand corner. When I tried adding the projects named inerpreter (or just Python 3.9.exe) it didn't work.
I was able to solve this by just copy and pasting the code into a new file, but that is not a permanent solution. Sorry for asking such a simple question, I wasn't able to find any searching for it.
