Could you help with the link at the end "?v=ebe021079e5a"?

Hello everyone, good evening. I would like to add a product to my site, but when I enter the product, something like "?v=ebe021079e5a" appears at the end of the product link. For example: https://domainname.com/?v=ebe021079e5a Normally, it used to open like this: https://domainname.com/. I think I made a mistake somewhere. I couldn't find a solution. Are there any friends who understand the problem?
