Corrupt Exported File

Hi. I’m pretty new and I use a Insprion Gaming labtop. I recently had a problem. After adding my normal intro and my footage recorded from obs, My mp4 file became corrupt. I changed the file type to Mov but had the Same problem. I uninstalled shotcut and downloaded it again but I had the same results. Can someone help me? (I only used shotcut for a month so I’m still pretty new).
