Guy friend stop talking to me?

I have a coworker guy friend who used to show me that he really cares about me, we both are married, and are considered good friends. He always buy me coffee, juice, sodas, and energy drink to start of my day. He used to share food with me, have me try his cooking, and even buy me food or candies to eat. He also buys my kids candies. We both used to always share each other funny reels too, and give life advices to one another. One night i went home early from work, he got me a coffee to drink, it was almost time for me to leave work, so i was chatting w another coworker before i go. He messaged me that our supervisor came to yell at him about why he didnt stop me from talking before i went home. I apologized to him and he said its ok, not my fault. but he began avoiding me now, he stop buying me coffee, and he would just walk pass me without saying hi or start a conversation w me. Were just like strangers now. Ive tried talking to him if hes upset about getting yelled at, and he said it isnt. But hes still avoiding me. He sended me reels, but deleted them before i even got to it. I ask him why he deleted it, and he ignored me. What do u think of this? Idk what ive done wrong.
