Sometimes Joomla forgets to copy some necessary files when updating or upgrading an extension. Download the package for the Pro version and install it twice in a row, without uninstalling it before or in between.

If this alone didn't help please delete the file administrator/cache/autoloader_psr4.php. This file will be regenerated automatically next time a page of your site is loaded. This file is created by Joomla based on the installed extensions' information, mapping PHP class names to the files on the server's storage which hold the code. Normally, this is updated every time you install, update, upgrade, uninstall, publish, or unpublish an extension. In some cases Joomla fails to do that, hence the need to remove this file.

These solutions apply to any Joomla extension using the native Joomla 4 API* when you get weird errors about missing classes.

* Note that a lot of the extensions available for Joomla 4 still use the Joomla 3 API through Joomla 4's backwards compatibility layer to Joomla 3. That's why you may have not experienced this problem just yet.
