The cover photo in the hero block is not showing

Your software
My Mautic version is: v4.4.10
My PHP version is: 8.0.30
My Database type and version is: 10.6.16-MariaDB

Your problem
My problem is:
The photo in the image block is normally displayed after sending the e-mail, and in the Hero block you can see the photo in the editor but it is not there after sending it.

These errors are showing in the log:
The log on the server does not show any errors

Steps I have tried to fix the problem:
If I add the same photo in the image block as in the hero background, the photo will be shown after sending. But when I change the photo in the image block, the background photo of the hero block no longer appears.
