Hi,
We would like some more information.
1. We understand that some plugins should not interfere but we ask that you please update them. This will help us rule out or in older plugins as the cause. This is especially true if you are using ACF plugins on the site.
2. Are you using any ACF plugins on the WooCommerce Product category pages? If so, which ones? Also, what ACF fields are in use on it? Text fields or something else?
We ask as the error message reported seems to imply you have ACF on the site and/or are using it on those category pages.
3. Does the issue resolve if you use a different browser such as Chrome or FireFox? Are they updated?
4. Does the issue resolve if you use another device such as another computer, tablet, or mobile phone?
5. If you have any browser plugins, does disabling them resolve the issue? Adblock and Privacy Badger are two popular ones.
