Can you reproduce this issue on default Wordpress theme (eg Storefront)?

Can you reproduce this issue when all other plugins are disabled except WooCommerce, Polylang and Hyyan WooCommerce Polylang Integration?

What product versions and settings are you using when this issue occurs?

PHP: Version 7.4.15
WordPress: Version 5.6.2
WooCommerce: Version: 5.0.0
Polylang: [state if using Polylang PRO] Version 3.0
Hyyan WooCommerce Polylang Integration: Version 1.5.0
Browser: Chrome

Steps to Reproduce

1. Start plugin and it crashes, deactivate in recovermode
2. deacivate and uninstall Yoast SEO end again starting Polylang plugin and it crashes, deactivate in recovermode

What I Expected

Start website normally

What Happened Instead

Site is again in recoverymode

Hi, you didn't state the the Yoast version, and the error log shows the error in the polylang plugin not this plugin.
there were Polylang fixes in 16 March 2021 release of Yoast SEO 16.0 and both Polylang and Yoast have had recent updates and should now be working.
This plugin itself doesn't interact with WPSEO.
