Hello,

I’m getting this crash when using Key variable in DataTable.

I was able to repro it in an empty project :

1. Create a Struct
2. Add a “Key” variable
3. Create a DataTable using that Struct
4. Open DataTable : Crash

Just found out the cause, when adding a Key variable, it’s set by default on None, which is the cause of the crash. Setting “Any key” would prevent the crash from happening.

Hi Genova,

Thank you for the report. I’ve created JIRA UE-22897 and our developers will be investigating the issue further. We will post back here with questions or updates as we have them.
