Hey @MoKeT79, welcome to the forums!  
I think you may have a memory leak. You most likely just have a nullptr that trying to be accessed. Here’s a link to a solved forum post about it, you may find the steps you need to fix it in there: [[SOLVED] Access violation - code c0000005 (first/second chance not available) - #2 by ExtraLifeMatt](https://forums.unrealengine.com/t/solved-access-violation-code-c0000005-first-second-chance-not-available/122905/2)

I hope this can help!
