Is it possible to return traffic to the site if there was a redirect from it before?

Question

Search Engine Optimization

In general, such a problem. There is a multilingual customer site. The main page is in English, there is a button for Russian. And from this button we decided to put a redirect to an external resource.
And it turns out that there is an English-language version of the site, but there is no Russian-language version, although the site is focused on attracting the Russian target audience. When I started working on the project, the redirect link was removed, but there was no traffic to the page. As far as I know, pages with a redirect fly out of the search within a month or two.
Tell me, is it possible to somehow return traffic to the page? It is still the main one, and the English version has traffic from the USA and the UAE.
