Linux: Exiting GameLauncher and ServerLauncher causes asserts to be printed to the Terminal

[LB-ArturZieba]

Describe the bug
Exiting GameLauncher and ServerLauncher causes asserts to be printed to the Terminal they were launched from (Linux).

ServerLauncher asserts:
Assert#1
File:

/data/workspace/o3de/Code/Framework/AzCore/./AzCore/std/containers/vector.h

Condition:

(140650960039040) 'AZStd::vector::const_reference AZStd::vector<AZStd::intrusive_ptr<AZ::Vulkan::CommandQueue>>::operator[](AZStd::vector::size_type) const [T = AZStd::intrusive_ptr<AZ::Vulkan::CommandQueue>, Allocator = AZStd::allocator]'
AZStd::vector<>::at - position is out of range

Line: 547

---

Assert#2
File:

/data/workspace/o3de/Gems/Atom/RHI/Code/Source/RHI/Object.cpp

Condition:

(140650960039040) 'void AZ::RHI::Object::add_ref() const'
m_useCount is negative

Line: 34

---

Assert#3
File:

/data/workspace/o3de/Code/Framework/AzCore/./AzCore/std/smart_ptr/intrusive_ptr.h

Condition:

(140650960039040) 'T *AZStd::intrusive_ptr<AZ::Vulkan::BufferPool>::operator->() const [T = AZ::Vulkan::BufferPool]'
You can't dereference a null pointer

Line: 189

---

GameLauncher assert:
File:

/data/workspace/o3de/Gems/Atom/RHI/Vulkan/Code/Source/RHI/Vulkan.h

Condition:

(140240341694016) 'void AZ::Vulkan::AssertSuccess(VkResult)'
ASSERT: Vulkan API method failed: Device lost

Line: 96

---

Full assert logs are attached in the Video and full assert logs section.

It should be noted that this issue only occurred on Linux.

Steps to reproduce

1. Follow steps listed here: https://github.com/o3de/o3de-multiplayersample/blob/stabilization/2305/README_LINUX.md to setup MultiplayerSample.
2. Launch ServerLauncher and GameLauncher as described here: https://github.com/o3de/o3de-multiplayersample/blob/development/README_LINUX.md#step-4-setup-client-and-server.
3. In the GameLauncher press Esc and click Quit in the menu.
4. Look to the Terminals used to launch ServerLauncher and GameLauncher.

Expected behavior
No asserts are printed to the Terminals.

Actual behavior
Asserts are printed to the Terminals.

Split into issues per assert

[LB-ArturZieba]

I have split this issue into separate ones per unique asserts as requested, they can be viewed here:

• Linux: vector.h(547) assert is printed to the Terminal when the ServerLauncher is closed #332
• Linux: Object.cpp(34) assert is printed to the Terminal when the ServerLauncher is closed #333
• Linux: intrusive_ptr.h(189) assert is printed to the Terminal when the ServerLauncher is closed #334
• Linux: Vulkan.h(96) assert is printed to the Terminal when the GameLauncher is closed #335

Closing the issue.
