My unity play button will not work. (SOLVED)

Recently, this game i made, a program on my computer took also 100% of the disk in Task manager then when i tried to click play on my game it didn’t freeze or say it wasn’t responding it just had the play darken and didn’t do any thing and didn’t have the blue on the button. not even the save button worked. Its not a very big project only like 5 scripts and at max 200 lines. I didn’t make changes to my scene so i don’t think is overloading.
(Note: It doesn’t respond when I build and run it.)

@a6085 Hi, its been about 6 months since I’ve used unity. But I think it was something to do with a “for” statement in an IEnumerator.
