I also find you (the OP) are making too many assumptions. Reading your message we (the readers) may just as well conclude your boss thinks your are doing good work and you are best left alone. Maybe your boss thinks you are a difficult person to talk to. The problem is informal discussion is difficult in those pandemic times although AFAICT everybody misses it. So if your boss is not making the effort to keep the link alive maybe you'll have to do it. Maybe he does not like you but still thinks you are doing good work. In this case a formal a one-to-one and asking directly what he thinks of your work is a better approach. If he both does not like you and does not like your work, there is not much to be done.
