Had argument with manager

I am new in a team and got a story assigned to me on Thursday afternoon. It was Friday morning and my manager was almost forcing me for 5-6 times to send the update on the story to client. As I work on VDI and it's too too slow, I was unable to go through the story properly, so forcibly, I had to send incorrect updates to client, to which they asked questions to my manager. And suddenly my manager's Second face revealed, and he asked me in the group "why did you send this incorrect update? You should have asked someone in team first. " (while he didn't give me some time to check with someone in team and forced me in the standup call to send updates at that time) and I was shocked, how this man turned his face within minutes!!!! When I justified my point, he started taunting me in the group chat, started argument and almost blamed me and shared the whole discussion to his manager and acted innocent. How these managers are so ruthless and double faced?? I am feared he would not approve my 1 week leave, I am planning to take during Dussehra or would give bad rating. Should I stay strong or apologize (even though I am not wrong )? Please suggest what should I do now???
