I read the new PN Yunus was a regular visitor to the US embassy. I would not be surprised if this was a way of the USA getting at India, for Modi paying his first visit to Russia. Same way they got rid of Khan in Pakistan when he didn't cancel his visit with Putin right after the start of the Ukraine war. India had huge influence in Bangladesh with Hasina. USA couldn't meddle too directly with India, since India is still a big part of their strategy against China.
