Can't access SP Pagebuilder Pro 3.7.12 in Joomla 4 Stable

[xomnis]

Hi,
I have tested the Pagebuilder with all J4 RC's but after the last RC 6 I get this error when I try to enter the SP Pagebuilder:
An error has occurred.
0 Joomla\CMS\Plugin\CMSPlugin::setDispatcher(): Argument #1 ($dispatcher) must be of type Joomla\Event\DispatcherInterface, Joomla\CMS\Application\AdministratorApplication given, called in /home/xxxx/domains/xxxxxx/public_html/libraries/src/Plugin/CMSPlugin.php on line 144
It's the same error after the Joomla 4 release launched today.
During the test I have updated SP Pagebuilder from 3.7.10 to 3.7.12 and I have an issue in the Maintenance: Database. It's still database version 3.7.10 and when I try to get the tables up to date nothing happens.

Hi,
I have found what causes this problem. The site is on a Litespeed server and uses a Litespeed cache package. I shall contact Litespeed about this issue for Joomla 4.
