Crash when opening and closing custom profiles and then closing UFE

Crash when opening and closing custom profiles and then closing UFE

Description

Semi sporadic crash is occurring when switching between profiles in UFE and then exiting out

This could not be repro'd on a Win7 machine with and Nvidia 980, could not be repro'd on a Win10 machine with an Nvidia Quaddro card, and could not be repro'd on a Win7 machine with a AMD 290.

Steps to Reproduce
  1. Open UnrealFrontend
  2. Create a Custom Launch Profile
  3. Hit the back button
  4. Edit the previously created Custom Launch Profile
  5. Repeat steps 3 and 4 approximately 5 times
  6. Close UFE

Result: Crash

This crash repro's about 1 out of every 5 times I try it
