vulkan unsupported backbuffer image count

Played harvest for a few hours (with vulkan)
Got a error and thought now its bed time.
didnt think to much on a error with harvest launch so i dont know what is said.
Now when i login, my settings are automatic put on directx.
When i try to switch back to vulkan after 1 minute of loading i get this error:

"unsupported backbuffer image count"

Is there a fix?

I am a very big fan of vulkan!
It really worked like a charm

Chipping in - I'm also getting an error for unsupported backbuffer image count. In my case, I get the error when initially trying to switch to Vulkan in the game start menu.

NVIDIA GeForce GTX 1060, version 443.24

Same here. At first, I played the new league like normal with no problems, but after I closed the game and opened it again it automatically went back to DirectX when I tried to switch it back to Vulkan "unsupported backbuffer image count" popped up.
NVIDIA GeForce GTX 1060

Same Issue =((

Same issue here. I tried to swap to Vulkan. PoE froze for a minute or so, then gave the unsupported backbuffer image count error and kicked me back to DirectX11.

Using NVIDIA GeForce GTX 1060.
