What's wrong with my raspberry plant?

Anyone dealt with this before? All the newest growth is turning brown. My other raspberry plants are fine, just this one is currently suffering.

Is it an older part of the plant? Is the floricanes (stem) brown and woody? Could just be at the end of life for that stem. I would suggest to prune it early/cut it at the bottom of the stem.
- It's all the way at the top of the plant. The stem it's on is still green though. A bunch of the leaves lower down are starting to look weird now too with this discoloration on them.
