Hi,
Do other applications have the same issue? Please go to Toolkit -> Configure -> Application profile -> Additional files tab to check if ‘Deploy Image Files’ setting is ok.
The special character in the image file name or folder name might cause the issue. please change the name without using the special character.

Please try removing files from the images folder that do not need to be deployed to the server or using exclusion method to gradually add configuration or files to find the root cause of the issue.
