Bing Instant Indexing

Hi team, I’m using RankMath on my two sites and decided to activate the new Bing Indexing feature. I activated on the first blog and it was ok. On the second blog, however, after putting Bing API it returns a critical error and won’t let me access my dashboard. I had to delete the plugin file from my cpanel to gain access back. Now I tried installing again and immediately it activates the same problem occurs. I can’t find a way to reset RankMath to disable the option.
