The operation couldn’t be completedwith the Cut Pro X

Hello tech experts,
When I am working with the Cut Pro X, I ended up with the following error message. The error message states that the operation couldn’t be completed. I am not able to understand the error message. I am not a technical guy; it’s very hard to explain in words. So I have attached the message. Please help to find the solution. Thanks a lot.

The operation couldn’t be completed.
