Hello [name]! Thanks for joining the GMC. Before making any posts in the Tech Support forum, can we suggest you read the forum rules? These are simple guidelines that we ask you to follow so that you can get the best help possible for your issue.
Can you please create a helpdesk ticket with the above information, your ui.log which can be found in \Users\Shared\GameMakerStudio2 and your project which causes this to occur. You can report this from within the IDE using Help > Report a Bug.
