So this bug log makes no sense to me. The game compiles but this spams quite a bit in my logs
What is this error? LogWindowsTextInputMethodSystem:Error: Deactivating a context failed while setting focus to the disabled TSF document manager.
Don’t worry about that error, it was removed in 4.6 due to the spam it caused.
It just means that the IME context couldn’t be removed from a given window, typically because that window hadn’t yet had an IME context set for it.
