Error: Cannot use object of type Drupal\Core\Render\Markup as array in Drupal\Core\Render\Renderer->doRender() [#2928668]

I use panels(8.x-4.2) and panels everywhere(8.x-1.0-alpha1) and I patched patch.
Current settings for pages: site template and node view are enabled.
When I open node(example.com/node/2) then i get error

I this should be solved by the patch from #2902488: Cannot use object of type Drupal\Core\StringTranslation\TranslatableMarkup as array. As you are using the alpha release, you don't get that fix because the fix was committed to the new 4.x development branch.
