Stack overflow exception when closing one form

Can't seem to find the issue.. I have a startscreen, and when any key is pressed on startscreen it takes me to the next form (frmLvl1). But this doesn't work anymore. Instead I get an overflow exception in frmLvl1 on a soundplayer. I tried to make the soundplayer a comment, but then it was just the next one that got an exception Here's the code: https://paste.mod.gg/ujqeprzayhyd/4 The exception in the screenshot is at line 26 in level1.cs
