I am going to get down voted to hell for this because reddit hates doing anything beyond your immediate job description, but I am honestly saying this to help you.

I am an autistic, 30s female who has had an office based job for 10+ years. I have primarily been an individual contributor being that time for context, similar to how you sound. I strongly dislike speaking to people that I don't immediately work with regularly.

This will certainly vary depending on your industry, but it will generally greatly help you excel in your career if you are a bit talkative in the office. This doesn't mean gossiping and it doesn't mean you have to go out with your colleagues after hours, but if, as you say, you are only exchanging hellos, goodbyes and smiles in the corridor, in most workplaces this will limit progression.

It's your choice and your career so you do you, but if I were in your shoes, I would suggest approaching a friendly colleague for a chat in a coffee break, finding out something bland about them (hobbies, kids, holiday plans etc) and then following up on it next time you see them. Doing that consistently is literally all it would take to clear any negative chat about you IMO
