The new problems in the Unwrapping

Good morning everyone and good morning sir
Please find the images that I sent
I did unwrapping for many stakes but now I have a problem, even I follow all the notes in tutorials and I did all the important points but still, I can not do the unwrapping.

Have you limited the processing to VV polarization?

Yes sir I chose VV polarization.
The process reach 19% after that stop and appear like the picture that I sent.
Thank you so much for your reply.

Apologies sir I solved the problem.
Thank you so much and I apologize for disturbing you.
Thank You
