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
I hope this can help!
