This happens due to some error in your file. Here is checklist of issues that you should check with the error causing designs

• There is a space at the end of the file name. E.g. “4thofJuly_1776USAFlagT-shirt_Merch_by_AMZN .png” You can notice the space at the end of the name and before the extension. Trim out the space and the problem will be solved.
• There is a special character in the file name that photoshop fails to read and write. Again renaming the file will fix the problem.
• Your files are in external drive, and photoshop does not have read/write access to the external drive, Move your files to the main hard drive and the issue shall be resolved.
• The design file mode could be index mode. Follow the video below to fix
