I just rewatched the clip of Wanda destroying the Darkhold Castle (recorded in cinema with the 1XBet logo, so I can't share the clip here) and a few seconds after her last shot in the movie when we see the rocks fall on here we see a red cloud of magic coming from under the collapsed castle as it collaps even further. Is this Wanda getting crushed under the rocks and her magic getting squeezed out of her? That red cloud means something, and I believe Wanda died. I love her character and WandaVision was greater then great, but I hoped her story is done and that she died during the collapse of the Darkhold Castle.
