Thanks for response, the extended information is:
Drupal\Core\File\Exception\InvalidStreamWrapperException: private://logo.png in Drupal\Core\File\FileUrlGenerator->doGenerateString() (line 112 of core/lib/Drupal/Core/File/FileUrlGenerator.php).

I also struggled with this same problem, after upgrading from drupal 7 to drupal 9.52. Any idea how to solve this problem?
