In a fresh installation on Drupal 11, I received the generic "The website encountered an unexpected error. Try again later." error message. In log file I found:
AssertionError: Cannot load the "date_format" entity with NULL ID. in assert() (line 261 of [...]core\lib\Drupal\Core\Entity\EntityStorageBase.php).
Investigating, I found a problem in: includes\_solo_theme_preprocess.inc. The problem in my installation is that
the output of
$d_format = theme_get_setting('site_node_date_format');
at line 712 is empty.
I solved adding another check, so lines 715 and further will be:
if (
$d_format !== 'none' &&
!empty($d_format<) && //adding this
!empty($variables['date']) &&
!empty($variables['display_submitted']) &&
$variables['display_submitted'] === TRUE
) {
Can anybody confirm?

Hello,
Thank you for reporting this. I can confirm this behavior occurs on a fresh Drupal 11 installation.
The warning has been resolved, and the development version has been updated accordingly.
Best regards,
