WooCommerce adds a strange addition to the site name

I have a page https://naruci.live/. However, when I run that page instead of this domain name, I get https://naruci.live/?v=5fc810cf6260. So, the suffix “?v=5fc810cf6260” is “glued” to the domain name. That part exists on all pages of this site. I deactivated all the plugins one by one, I replaced the theme and got the result: This part “?v=5fc810cf6260” does not exist when I deactivate WooCommerce. When I reactivate WooCommerce, this plugin appears again.

This causes a problem when I try to optimize the pages. I get a message that there is an error and this part is highlighted in red.

The page I need help with: [log in to see the link]
