Route "update.theme_install" does not exist.

Hi stenbisschop,
I am not getting any error while install the module and also i checked the code, no code related to error might be cache issue.
Drupal: 10.4.1
php :8.2

Thanks!

I think it's not the styleguide module itself, but it's causing by this issue: https://www.drupal.org/project/admin_toolbar/issues/3503934 🐛 Route "update.theme_install" does not exist Active

I also thinks it's Admin Toolbar.
