Of course, some people can't get acquainted with others quickly because of their personality, so they will feel this way in a short time, and it will be good after a long time.
If you really feel this way, I suggest you start with people in your office and talk to them often. By chatting, you can get to know other people in the company quickly. Of course, you should also find out your own reasons, whether it is because you don't actively integrate into this company or other reasons.
