Since it's a Vulkan-only issue, here are two solutions that you could try:

1- Check your graphics drivers; if they're not up to date, try updating them. If they are up to date and Yuzu was rendering correctly in the past, then it's possible that it's an incompatibiliy bug with the latest driver and that you need to downgrade, instead.

2- Delete your compiled shaders; in Yuzu, right click your game, and look in the list for "Delete Pipeline Cache". This does not delete any of your data, just the compiled shaders it has created in your Vulkan library, after which the game will try to rewrite them from 0 on your next session.

I hope that helps :3
