Development Programming & Scripting

hello when i build in visual studio 2022 it gives me this error:
3>UnrealBuildTool : error : Unable to build while Live Coding is active. Exit the editor and game, or press Ctrl+Alt+F11 if iterating on code in the editor or game

i tried pressing ctrl alt f11 like it said but then i got this error
ERROR: Unable to patch action graph - unexpected executable in compile action (C:\Program Files (x86)\Windows Kits\10\bin\10.0.19041.0\x64\rc.exe)

its just annoying to have to reopen the project and wait every time i make a little change, does anyone know how to fix??

What if you disable live coding?

You should close the editor everytime you compile in Visual Studio. The live coding / hot reload feature is experimental and causes corruption. No clue why UE still has it.

I’m using VSCode and recompile in the engine. Sometimes you do have to reload, but in most cases you don’t. You can try VSCode if you want.
