PageBlockDisplayVariant::__sleep() is no longer compatible with parent signature from ctools leading to PHP fatals

I have created the patch to fix the issue.

Created a MR with the patch#2 as it's a trivial change so would be better if its merged straight away.

A screenshot is not necessary.

Concise title.

Critical since it completely borks a site.

Proposed changes seem fine.

Working on it. Theres a few other page manager things I gotta look at today as well, but will prioritize this since its breaking builds. In the meantime, you can pin ctools to 4.0.4.

This is fixed in the D11 readiness issue

Hi,

Total noob here. How do I apply the patch on this page to my Drupal installation?

@devaper if you want a patch, go to the MR page and append `.patch to the number.

e.g https://git.drupalcode.org/project/page_manager/-/merge_requests/21.patch

Make sure you download the patch to your site, not reference the URL, as the URL contents can theoretically be changed by anyone.

Thank you.
