ERROR: "The command setlocal" about godot-native-example HOT 2 CLOSED

Yeah, you were dead right, the reason for this Error was that godot was running in the background. It doesn't matter if it crashed because of an error or someting. Running apps in godot must be properly closed with F8 so it works. There has been one instance were the error occured even though everything was closed, but this happend once and resolved itself very quickly.

I know we have probably a found the issue, but heres the whole build output since you asked:

from godot-native-example.

Can you paste the whole build output? CMake/Visual studio integration sucks so the error is actually before this.

However, my guess... the install task copies the built dll into the example directory. Maybe you're building with Godot and the dll loaded so Windows has locked the file and won't let you overwrite it.
