 * Hi [@kayahnung](https://wordpress.org/support/users/kayahnung/)
 * The errors you’re experiencing appear to be related to the registration of Gutenberg
   blocks. These blocks are part of the WordPress core or themes and should not 
   cause any issues with the functionality of WooCommerce or the setup wizard.
 * However, to ensure a smooth experience, I recommend taking the following steps:
    1. Clear your browser cache: Sometimes, cached files can cause conflicts or errors.
       Clearing your browser cache can help resolve these issues.
    2. Disable any browser extensions or add-ons: Some browser extensions or add-ons
       may interfere with the proper functioning of the setup wizard. It’s a good idea
       to disable them temporarily to see if the errors persist.
    3. Update your plugins and themes: Ensure that all your plugins and themes are 
       up-to-date, including both WordPress and WooCommerce. Outdated plugins or themes
       can sometimes cause conflicts with the latest versions.
    4. Check for plugin conflicts: If updating your plugins and themes doesn’t resolve
       the issue, try deactivating all plugins except for WooCommerce. If the errors
       disappear, reactivate your plugins one by one to identify the one causing the
       conflict.
    5. Enable debugging: If none of the above steps resolve the issue, you can enable
       debugging in your WordPress installation by following the instructions in this
       guide: [https://wordpress.org/support/article/debugging-in-wordpress/](https://wordpress.org/support/article/debugging-in-wordpress/).
       This will help you identify any underlying issues that may be causing the errors.
 * If you have followed these steps and are still experiencing issues, please share
   your **System Status Report**, which you can find via **WooCommerce > Status**.
   Select **Get system report** and then **Copy** for support. Once you’ve done 
   that, paste it into your reply here. This will help the WC support team investigate
   further and provide a more accurate solution.
 * I hope this helps! Thanks!

 * Hi [@kayahnung](https://wordpress.org/support/users/kayahnung/),
 * Thank you for reporting this!
 * This is a known issue introduced in WooCommerce 7.6.0, but as [@shameemreza](https://wordpress.org/support/users/shameemreza/)
   explained, it shouldn’t affect the functionality of WooCommerce.
 * It will be fixed in WooCommerce 7.7.0 (you can check the fix [here](https://github.com/woocommerce/woocommerce/pull/37350)).

 * Hi [@juliangk](https://wordpress.org/support/users/juliangk/)
 * Thanks for reaching out!
 * I understand you are experiencing the same issue and since every site is different
   and you’re not the person who originally started this topic then, per the [forum guidelines](https://wordpress.org/support/forum-user-guide/faq/#i-have-the-same-problem-can-i-just-reply-to-someone-elses-post-with-me-too),
   would you please [start your own topic](https://wordpress.org/support/plugin/woocommerce/#new-topic-0)?
 * Additionally, please include your **System Status Report** that you can find 
   via `WooCommerce > Status`. Select `Get system report` and then `Copy for support`.
 * If you could also provide the **fatal error logs** (if any) under `WooCommerce
   > Status > Logs`.
 * Once you’ve created a new forum topic, you can include the contents of your SSR
   and logs within your message on that forum topic.
 * We’ll be more than happy to help there 🙂

 * Hi [@juliangk](https://wordpress.org/support/users/juliangk/), thanks for reporting
   additional info!
 * I tried to reproduce this issue on a new site with WooCommerce 7.7.0, however,
   seems it is a different issue. It looks quite similar at first glance but it 
   is caused by other components and a different reason.
 * In 7.6.0:
 * Block “core/paragraph” is already registered.
   Block “core/image” is already registered.
   Block “core/heading” is already registered.Block “core/list” is already registered.
   Block “core/list-item” is already registered.Block “core/quote” is already registered.
   Block “core/video” is already registered.
 * In 7.7.0:
 * The block “woocommerce/product-radio” is registered with an invalid category “
   woocommerce”.
   The block “woocommerce/product-section” is registered with an invalid
   category “woocommerce”.The block “woocommerce/product-tab” is registered with
   an invalid category “woocommerce”.The block “woocommerce/product-schedule-sale-
   fields” is registered with an invalid category “woocommerce”.The block “woocommerce/
   product-track-inventory-fields” is registered with an invalid category “woocommerce”.
   The block “woocommerce/product-sku” is registered with an invalid category “woocommerce”.
   The block “woocommerce/product-checkbox” is registered with an invalid category“
   woocommerce”.The block “woocommerce/product-shipping-dimensions-fields” is registered
   with an invalid category “woocommerce”.The block “woocommerce/product-shipping-
   fee-fields” is registered with an invalid category “woocommerce”.
 * We are working on it, and as [@xue28](https://wordpress.org/support/users/xue28/)
   suggested, this would qualify for a different topic so please feel free to report
   it separately if you’d like to follow up on it.
 * Thank you so much!
