Fatal error : Cannot declare class Piwik\Plugins\CoreHome\Columns\LinkVisitActionId, because the name is already in use in /matomo/plugins/CoreHome/Columns/LinkVisitActionId.php on line 33
Could you try remove all Matomo files again (except for config/config.ini.php in case you could finish the install) and then copy over the files again. We haven’t heard of anything like this before and our tests don’t show such an error?
