I'm using the latest version of SP Page Builder and Joomla 4 and I'm encountering a similar issue that others are having – getting the 'COM_SPPAGEBUILDER_MEDIA_MANAGER_MEDIA_TOTAL_SIZE_EXCEEDS' message when trying to upload through the Pagebuilder. I've contacted my webhost 1&1 / Ionos and they changed the memory limit to 512M and even 768M, neither of which helped. I'm able to updload through the Joomla media manager and FTP, but it would be nice to be able to upload directly through Pagebuilder. Is there anything else I can try?
