Bug Description

Components with AZStd::string crash O3DE Editor when added to prefab and when the value change (as an override) is followed by the [ENTER] key.

Assets-Required

Test prefab was used: https://github.com/jhanca-robotecai/O3DETestProject/blob/development/Prefabs/TestPrefab.prefab to isolate the issue; the whole project can be used for tests (commit 6d78645)

Steps to Reproduce

1. Create a prefab with a component that has AZStd::string field
2. Add this prefab to your scene
3. Change the value of the string in the override mode
4. Press [ENTER] key to change the focus from the line edit back anywhere
5. Segmentation fault

Note: the Editor does not crash when changing the focus from the line edit with a mouse click

Expected Behavior

The focus of the line edit is lost; the name change is applied; the Editor can be used

Actual Behavior

Segmentation fault
