Why The CW is not recasting Batwoman Explained

The CW Will have a New Batwoman come 2021 and we now know how & why the decision was made, coming from the virtual ATX Television Festival Caroline Dries  explains it. SOURCE

"So, to be honest with you, I did consider the soap opera version for a hot minute, selfishly, because we had a couple episodes already written, and transition-wise, it would be seamless [since] we already started breaking season 2," Dries said. "But upon further reflection, and Greg helped me make this call and he's way smarter than me about this sort of stuff, he's like, 'You know, I think we should just reboot the character in terms of reboot Batwoman as a different character.' Just to also respect everything that Ruby [Rose] put into the Kate Kane character."
