Sage has all of a sudden stopped compiling my code. It happened seemingly out of nowhere and im getting very worried because i spent ALOT of time writing an algorithm. Basically nothing happens when i run the code the long grey line comes up with a green bar flashing and the normal output rectangle but it jsut stays in that state permanently. Nothing seems to fix the problem, i've tried going back in the history, copying and pasting to a new folder and worksheet changing the code, trying to get literally anything to compile but to no avail. Im literally dumbfounded at the moment.
