Config page fails to load due to missing default value for logo_file

Hi @harsh.behl,
I have fixed this issue by adding default value for logo file and also created MR . Kindly review the changes.

Thank you.

This makes the configuration page accessible without a white screen error, but the logo image (I used a png) won't be used in the generated QR codes. Also, if you have config_enforce module enabled, saving the admin settings form for the first time without changing anything but uploading the file, will give this error:

Also for completeness, this was the error without the MR just by accessing /admin/config/endroid_qr_code right after installing on a fresh Drupal 10.1.4 site:

And.. I noticed the QR codes are never shown when viewing a content entity but somehow they show in the preview of Views showing fields (and not the rendered entity)?!

This looks great. When I initially tested it did not work, but it was because I already had the module installed before applying the code in the merge request. After uninstalling the module, and reinstalling, the active config was updated and the config page was functional. Thanks very much for the fix.
