Audacity won’t open my files

Guys I need help. I’m using Windows 10 with Audacitu 2.3.3 and it kept on giving me problems while I was editing a file. Then all of a sudden it shut down. Completely. Now when I open the file it shows the stems with a long line as if there’s no audio. And when I try press play it either freezes or it says no memory. Please help! It shut down while I was editing a song. Literally on the last 2 steps.

What is the full and exact error message?
