It's frustrating when software doesn't work. It makes you feel like your time is being wasted, and there's nothing that can be done to fix it. It's demoralizing and destructive to the creative process.
Fortunately, Apple has a helpful link where you can troubleshoot Logic Pro issues:
https://support.apple.com/en-us/HT200260
If Apple's solutions don't work for you, feel free to reach out.
Sometimes a second opinion is all it takes to get Logic Pro working again--and without wasting any more precious creative time than is necessary.
The Logic Studio Training support form is the best way.
