(PS5/PC) Immortal of Aveum Lash anchor not working

Playing on PC via Steam.

Chapter 8 - Exile

Grapple stopped working after initially no problems.

1. Acquired Grapple in Shroudfane
2. Used Grapple in Shroudfane and exited fane.
3. Traversed Leyline to meet and talk with Devyn.
4. Traversed Leyline to new map/level Oremen
5. Used leyline traversal and grapple some more, fought some fights.
6. Fought Corruption worm
7. All grapple icon appear grey, grapple not working anymore
8. Reload - no change
9. Quit and restart - no change
10. Restart chapter
11. Acquired Grapple in Shroudfane
12. This time, grapple is not working from beginning, even in the Shroundfane
13. Cannot progress Shroudfane
14. Triggered "Validate game files" in Steam (no issues detected)
15. Restart chapter
16. Same problem, doesn't work even in the Shroudfane
17. ...now what?

All advice appreciated...

im having the same issue on pc in chapter 9. literally cant even continue the game because i need to grapple to get to the next area and it wont work. his hand does the animation but nothing happens. this is the first game ive ever played where ive had a gamebreaking bug to the point i cant play it lol

I am having the same issue on PS5. Game reinstall, chapter restart did not fix the issue. See video attached for exact spot where grapple/anchor point isn't activated.

Hi. 
no prompt. I try jumping and hovering closer but it doesn’t prompt a lash.
