After updating to 2.0.12 no recipes are showing at all in the "Recipe Selector", no matter what options I enable or disable.
Even when trying on old "Production Lines" no recipes will show.

Picture of what it looks like: https://snipboard.io/rFYVzp.jpg.

I've tried backdating to an older version, but I still have the same problem.

Tried making a new save, got an error message saying this: https://pastebin.com/udReMWWP

It's strange, I have no error when I try new game.
can you share your saved game?

I will try when getting home, though its worth mentioning its a modded playthrough. I have tried disabling the mods, to no difference.

Okay so with some tinkering ive found out its probably one of the "production lines" which is already on the save that's causing the problem. Is there any way to clear the lines from file explorer? Surely they are cached somewhere seeing as how no matter how many times I reinstall the mod the production lines persist.

The "Recipe Selector" is not affected by production line, but you can use the admin menu, top right icon on helmod panel and regenerate cache.
To delete production you can use the delete button on the line production.
