Dual gtz 1650 and gtx 750 error on Vulkan

I recently acquired a gtx 1650 graphics card with which yuzu works correctly with vulkan, after that I put my old gtx 750 card, both at the same time on the motherboard, and for some reason Yuzu no longer allows me to use Vulkan.

I know that the gtx750 does not support Vulkan at all but the gtx 1650 does, so my question is why does Vulkan work with a single card and not with 2. Being the two cards 750 and 1650 yuzu sends an error.

here is a copy of the log file :

In order for us to provide better support, we need to see the log generated by Citra. This guide will walk you through how you can obtain the log file: How to Upload the Log File.

Make sure you are running the latest GPU driver from Nvidia, it will cover both cards fine.
Expect very low performance with an FX CPU.
