The Editor will crash while opening a project that had previously successfully had a Live Coding patch applied, and then was closed. The `LiveCodingConsole.exe` process continues to run after both the Live Coding console window and the Editor have been closed, and this still-running process apparently interferes with the Editor opening. Making sure that the still-running `LiveCodingConsole.exe` process is ended before opening the project again in the Editor allows the Editor to open the project successfully.
REGRESSION:
No. Live Coding is a new feature in 4.22.
RESULT:
The Editor crashes due to an unhandled exception while opening shortly after the Live Coding Console window appears.
EXPECTED:
The Editor opens the project successfully.
WORKAROUND:
Make sure the still-running `LiveCodingConsole.exe` process is ended before re-opening the project.
