Do I need to use Open Graph markup in this case?

Question

Search Engine Optimization

Greetings. I will try to keep it short and clear.
This is a common example of Open Graph markup that can be found on the Internet:

<meta property="og:locale" content="ru_RU"/>
<meta property="og:type" content="article"/>
<meta property="og:title" content="<?php echo $title;?>"/>
<meta property="og:description" content="<?php echo $description;?>"/>
<meta property="og:url" content="https://site.ru"/>
<meta property="og:image" content="https://site.ru/image.jpg"/>
<meta property="og:site_name" content="site_name"/>

However, when using it, it turned out that the last meta tag og:site_name in search engines adds the site name to the title , getting instead of
Title
Something like this:
Title - site_name

In other words, all SEO is ruined. Perhaps, for large old sites, this, on the contrary, plays into the hands, but for the rest ... it will usually be, oh, how not sweet. Therefore the question. There are very different proposals on the net: Remove the entire Open Graph or just og:site_name? - I ask to prompt more experienced people. Since the markup itself is very convenient for social. networks, because when inserting links into a post, the necessary picture and other information is immediately added, and I would not want to delete all of it. I would be glad to hear any thoughts related to optimization

In my opinion, the opengraph markup does not affect SEO in any special way, just a Facebook "hint" that your crooked titles were flooded and the site began to fall out .... then there are quite a lot of options that grabbed the filter, there is not enough content for the search engine to determine the title for pages (for a long time what you write in the title tag is not displayed in the search engine results, the search engine based on the content itself determines the relevance of your page to the query and what phrase to display to the user based on this query), here you need to work with the content, well, it’s quite possible that this just reindexing the search engine determined that something has changed and tried to reindex the content....
In general, you need to decide that there are no gross SEO errors (404, pages without text or a bunch of spam in texts, are all meta tags spelled out, etc.) and there are no bans ... (if this is Yandex, then I wrote in support that so and so the site was in the top for such positions, and today everything fell down and brought screenshots, could you answer it like this, the search engine re-ranked the site or I have some kind of ban and always answered, Google just had an inscription), well, if everything okay.... I would work further with the content, add new useful descriptions to existing pages, so that the search engine would continue to notice "work" with the site and return positions

Lord. Before answering or writing comments, please read this message.
The site fell out of Yandex right before our eyes. In Google - only those pages remained clickable, to which the site_name was not assigned. And some people are still asking what could be wrong??
The only question is: Remove the entire Open Graph or just og:site_name? I would really appreciate hearing thoughts on the case. This is the first time I’ve encountered similar problems with this markup, so suddenly it still promises some kind of trouble.
