    I suddenly get this on the android version of my game and would need some help to analyze how to fix it:

    Code (CSharp):
    1. Thread 0 (crashed)
    2. 0   libunity.so                        0x0000007e33ada15c GfxDeviceVK::EnsureValidBackbuffer(vk::SwapChain*)
    3. 1   libunity.so                        0x0000007e33ae9664 vk::RenderPassSwitcher::InternalApply(vk::CommandBuffer*)
    4. 2   libunity.so                        0x0000007e33acdd80 GfxDeviceVKBase::EnsureCurrentCommandBuffer(vk::CommandBuffer::Type, bool)
    5. 3   libunity.so                        0x0000007e33ac975c GfxDeviceVK::ClearImpl(GfxClearFlags, ColorRGBAf const*, int, unsigned int, float, unsigned int)
    6. 4   libunity.so                        0x0000007e33de81f8 GfxDeviceWorker::RunCommand(ThreadedStreamBuffer&)
    7. 5   libunity.so                        0x0000007e33dee8a0 GfxDeviceWorker::RunExt(ThreadedStreamBuffer&)
    8. 6   libunity.so                        0x0000007e33de6c20 GfxDeviceWorker::RunGfxDeviceWorker(void*)
    9. 7   libunity.so                        0x0000007e339e23a8 Thread::RunThreadWrapper(void*)
    10. 8   libc.so                            0x0000007e57b71258 <system symbols missing>
    11. 9   libc.so                            0x0000007e57b26c00 <system symbols missing>
    12.

    Thanks for answering. Interesting for me is that it does not show up every time.

    Is anyone able to reproduce these crashes and could submit a bug-report to Unity, please?

    I see this crash a lot in Cloud Diagnostics as well, but I'm unable to reproduce it. I'm afraid when nobody submits a bug-report, with a project that Unity Technologies can use to reproduce the crash, this issue persists.

    No, I am afraid I cannot recreate this at this point.
