@grdbum, You need to be more specific regarding the steps of the crash that you experienced. Also, which version of Shotcut are you using?
Right now there is a Beta version of the next release that you can find here. It’s meant for testing out any bugs and crashes so that they can be fixed for the official release. You should download that Beta and see if the problem you are experiencing in your current version of Shotcut still happens in the Beta. If it does, report it in that thread and be specific about the steps to reproduce the crash so that it can be found and fixed.
