Anno 1800 random crashes with "Unespected DirectX error" and VK_ERROR_DEVICE_LOST

[juliotux]

Anno 1800 randomly crashes after some time of game play. The time or action this occurs seems to be random. When it freezes and crash, a small window pops up like the screenshot bellow.

This problem happens with DX11 and DX12.

It also show some messages in the terminal:

err:   DxvkSubmissionQueue: Failed to sync fence: VK_ERROR_DEVICE_LOST
err:   DxvkSubmissionQueue: Command submission failed: VK_ERROR_DEVICE_LOST
wine: Unhandled page fault on read access to FFFFFFFFFFFFFFFF at address 0000000142D6B52D (thread 04a4), starting debugger...

Can't reproduce, game works fine on my system

Guess the Nvidia driver just crashes for some reason, maybe see if dxvk.halveNvidiaHVVHeap = True in dxvk.conf does anything. Given that no relevant DXVK code is involved when running the game in D3D12 mode, it is extremely unlikely to be a DXVK bug.

@doitsujin investigating it a bit more I found that this problem also appear for some users in Windows. So, it seems to be a Anno bug.

I can confirm that this bug happens on vanilla Windows. It occured often to some of my friends in Online play - all using Windows. One of them has a 5600XT so doesnt appear to be Nvidia specific.
