Vulkan: Standalone Build crashes, API Compatibility .NET 4.x or Standard 2.0... what to use then?

This known issue "Vulkan: Standalone Build crashes when the build is made with API Compatibility Level with .NET 4.x or .NET Standard 2.0" - aren't those the only two options now? We've been trying to solve Vulkan crashes in our Linux builds, just switched to 2019.3 to see if that helps, but then I see this, and am perplexed. The bug doesn't list a workaround or anything.

 

Ah - then the known issue should really be "Vulkan: Standalone Build crashes", which API compatibility doesn't matter when the only two ones cause crashes. That's where my confusion came from ("which is the third API I can choose to not crash, if those two crash?")

Unfortunately, I cannot submit a bug report yet for the crashes we get in Linux, because I have no idea at all what causes them yet so I can't create a small project to replicate them (and I can't send our full project). Our project is very complicated and not only like 15GB but also very sensitive. All I know right now is that it crashes in Unity 2019.1 and 2019.2 with no error but a Vulkan call as the top call in the call stack (though a null exception in Vulkan is mentioned in 2019.1), and it happens when the resolution is too high, or the quality settings too high, or when the app is full screen, or when what we are rendering gets too intensive, or if the editor is running (acting as if it were a memory issue, but doesn't happen in Windows, and the machine in question has a 1080ti and 128GB RAM).

My current test was to try upgrading to Unity 2019.3 to see if the new HDRP or Vulkan bugfixes will help with the situtation

 

I've narrowed the Vulkan crash down, happens when there are more than one camera active at the same time. And this particular project can have 3 cameras going at once, including one rendering to a rendertexture, one aimed at a UI RawImage rendering that rendertexture, and a normal camera (all of the cameras have background color sky or solid color)

 

Hello,
Did you found a solution ?
I've got a project using between 2 and 6 cameras and project doesn't work, but a simple project using HDRP doesn't work too.
I've upgrade from 2019.4.4 to 2020.1.1f1 and HDRP too but nothing changed.

 

Hello,
Did you found a solution ? I get the vulkan crash for android,by unity version 2019-3-7f1
