There are a few issues with PHP 8.4, all of them related to the implicitly nullable parameter being deprecated now, requiring an explicit marking declaration.
I see the issue 🐛 Deprecated: PHP 8.4 Active fixed a few, but a couple still remains, most specifically for the Context UI submodule.
Checking the code using PHPCompatibility code sniffer:

I've created a merge request with the fixes for the PHP 8.4 deprecations.
I'm also attaching here a patch file for the same fixes, for composer patches.
Please let me know if you have any questions. Thank you.
