Hi,
I also see the same error, SINCE I updated o the latest wordpress version (5.5.3).
It only happens when the “WooCommerce Admin plugin” is active, when I cannot access anything related to WooCommerce (Version 4.9.2) or its settings in the dashboard. When I disable this plug in the error goes away and I can access WooCommerce settings.
WordPress version 5.5.3
Current theme: Storefront (version 3.5.0)
Current plugin: WooCommerce Admin (version 1.9.0)
PHP version 7.4.14
