Greetings @harshgehlot1
Welcome to the Unreal Engine Forums! In regards to the crashes that you’re having, are you able to take a screen shot of the crash log when it pops up? Also, is this issue only happening on one specific project? (I pulled a link to other users experiencing this type of issue that I’d recommend taking a look at as well. Here’s a link to the post. Hopefully this is helpful!)
