Unknown problem using altool

Ive been Notarizing fine on a several times a week basis. Now today I am receiving an error Notarizing.

`Unknown problem using altool. Check that the app-specific pasword, Apple ID, and team provider name are correct.`

Log shows: 16:59:45.336: Unknown problem using altool. Check that the app-specific pasword, Apple ID, and team provider name are correct.

They are positively correct.

Any suggestions on how to resolve would be appreciated.

Looks like I answered my own question. No idea how or why but Xcode’s active developer directory somehow changed between today and Tuesday. I had to reset to the default command line tools path

I figured it out when I tried to manually test notarization tool:
xcrun altool --list-providers -u usernamehere -p passwordhere

and received the following response:
xcrun: error: unable to find utility "altool", not a developer tool or in PATH

Fixed it by reset to the default command line tools path since I knew it was installed:
sudo xcode-select --reset

By chance if anyone wants the commend to install if the command line tools are not installed and want to do from command line:
sudo xcode-select --install

Hopefully this helps someone in the future.
