First, it is possible that you two have different understandings of professional technology and professional skills, so communication is not on the same channel. One person is right, one person is wrong, or one person is too knowledgeable to communicate well. In this case, if it is not the same level, don't communicate, find someone at the same level, or find some authoritative people to communicate, so that things can be solved quickly.
Secondly, the second reason is that you and his emotional intelligence are different, that is to say, two people have different personalities, so they can't get along with each other, resulting in the G limit of two people. This is a situation. Another reason is that it is difficult for two people to communicate with each other, because they are compared and, well, have the same personality. If two people have different personalities, then one is stronger and the other is weaker, and it may be easier to communicate. If two people are strong and can't tolerate each other, this will also result.
How to solve this problem when this happens? First of all, a more impartial person is needed to be the referee. If it is really impossible to communicate, then each of them will hand over their own problems to the supervisor. Another way is to say that two people do different things separately and wonder if they can do the same thing. In other words, two people are investigating two different tasks, so there is no contradiction or intersection between them. This can avoid the contradiction between two people's work.
