Ocean-extra and add-polylang-support-for-customizer

Good day
I have since several months problems with the plugins “ocean-extra” and “add-polylang-support-for-customizer”.

So I update ocean-extra and the site is no longer accessible in the font as well as in the backend. I have to FTP in and manually remove the plugin ocean-extra and import a previous backup to get everything working as it should again.

WordPress version 6.2.2
Active Theme: OceanWP Child (version 4.20) | OceanWP (3.4.7)
Current Plugin: Add Polylang support for Customizer (Version 1.4.5), Ocean-extra 2.0.6
PHP version 8.0.29

An E_ERROR type error occurred on line 136 of the file /homepages/0/d791733612/htdocs/xxx/wp-content/plugins/add-polylang-support-for-customizer/includes/class-apsfc.php.

I can always reproduce the error by updating ocean-extra.
If more information is needed, I will provide it.
