David Lynch has died

I'm so grateful he was able to make Twin Peaks: The Return before he passed. It's one of the most brilliant and moving pieces of fiction I've ever experienced. If they had started it just a few years later it may have never been finished.

Some of the people who returned for it died not long after it wrapped. The "Log Lady" might have died before it wrapped, even, can't recall. Miguel Ferrer wasn't around much longer. Even with Lynch living a good while past it, it'd have been far more limited production if it'd started even a couple years after it did. They already had to do without Bowie and a few others that it seems Lynch might have liked to use (given what he did with the season), like Frank Silva (BOB) of course, and notably Don Davis (Major Garland Briggs).

Yes, she was terminally ill and in hospice care. Lynch moved up the filming of her scenes as well as writing the part so she wouldn't need to travel. The fans really embraced her in the years after the original show aired, inviting her to conventions, etc. She wanted to finish her character's role for the fans before she died.
