Build Type: Binary.
Build version: 4.11.1-2934540+++UE4+Release-4.11
Detailed description of the issue: When I try to add a row to any data table my editor crashes. This started happening a few minutes ago but has a 100% repeat rate. I was using a structure made in C++ for my data table. It already had data in it. When I tried to edit one of the rows that was already created the editor crashed. I tried making a new data table, recompiling C++ code, and restarting the editor.

Screenshots/Link to video: N/A.
Repro Steps: Create a data table, user defined or from a struct made by UE, and try to add a row to it - the editor will crash.
This happens 100% of the time.
System Specs: Windows 10, intel 2500k @ 4.3ghz, 14gb ram, GTX 760.
Attachments: N/A.
EDIT: This now happens to every project I use. It makes the editor unusable for what I’m trying to do right now.
EDIT 2: I followed what they said here and clicked Window → Reset Layout. This seemed to stop the crashing.
