error Linking assets failed. Run CLI with --verbose flag for more details. Error: Source and destination must not be the same

I am linking assets for the purpose of using external custom fonts. The fonts folder is in './android/app/src/main/assets/fonts/'. 'react-native link' does not work but 'npx react-native link' works, but with this error.

Would be great if somebody solved this problem. Thanks in advance!
