Hi,
I am using a Mac (Apple silicon) to develop a Matter device. We are using one of the Matter examples, but when importing the example we get the error that GN Tool cannot be found. We have installed a PATH to the GN tool location and we can run the GN Tool from any library path of the SDK library, so we cannot understand why we get the error.
Here is the error message:
