AssertionError: Cannot load the "date_format" entity with NULL

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,

    Hello,

    The same error occurs with Solo 1.0.20 on D10.5.1, producing a WSOD with the message:
    "The website encountered an unexpected error. Try again later."

    In the logs, here what is displayed:

    Message:

    This doesn't occur if Solo is disabled and Olivero enabled instead, or if Solo 1.0.x-dev is used.

    Therefore, do you know when the new stable Solo version is going to be released?
