iPhone automatically presses enter while typing, starting new line

Hello I recently bought IPhone 16 pro max and I have issue iPhone automatically presses enter while typing, starting new line 

This is a very annoying problem. When I seek to type a sentence on my iphone, the phone will often automatically press "enter" forcing me to begin a new line of text, even in the middle of words. 

Below, I have shown how this message appeared when I tried to type it on my phone without correcting for this problem.
