Retroarch 1.7.1 Crashes When Using Vulkan

I updated to RetroArch v1.7.1 today and everything runs fine except when I use the Vulkan driver RetroArch crashes whenever I Minimize it. I updated all my drivers and that didn’t help. When I use opengl and D3D fixes the problem but I like using Vulkan because it runs faster and smoother than opengl or D3D. Also, I have no problems with any stand alone emulators such as dolphin or PPSSPP using the Vulkan front-end. And I didn’t have any problems with the previous version of RetroArch when using Vulkan. Any help with this would be greatly appreciated.
