Access Violation Issue

Hey guys, I’ve been working on this Game for School for a while now, I took about a month break from working on it and i come back and i see that Visual Studio cant start the game up anymore. It says:
The program ‘[9584] GoldExp.exe’ has exited with code -1073741819 (0xc0000005) ‘Access violation’.

It doesn’t make any sense, because compared to the last time i tested it, i literally added in nothing new, it should still work. The only thing i did Differently was i had to Log into Visual Studio. Anyone have a Solution to this, I really kind of need to finish it.

Access violations happen in native code (C, C++). What was the last line of C# code before the access violation? Are you familiar with debugging?

If you are absolutely sure your program didn’t change, then something about the environment must have changed, in which case reinstalling stuff that’s relevant to your program might do it.
