Operations that done before the error occurs:
I was using the UV edit function and adjusting the rotation of the plane tool. I was going back and forth applying it and rotating it when it inexplicably closed the program. Once reopening the program no crash report was seen and no prompt to recover lost data was issued.
Windows 10 Home, 64bit Operating System.
