MySQL Plugin (error with select)

Hello,

I currently have a problem with the MySQL Integration plugin (available here: MySQL Integration in Code Plugins - UE Marketplace)

When I want to perform a Select to get the data from my table, the game crash with this error : Screenshot - 7f147c2b54242ac6b5933aca0858b752 - Gyazo

Here is select (when i’m open my menu, select launch) :

Here is PopulateData function :

And here is DisplayMessage function :

My DBConnectionWidget (Database configuration) :

If you have an idea do not hesitate, i don’t why i have this problem, i search since 3 days but i found nothing.
