What's the problem? Describe what went wrong.

Upon starting any game with the direct3d11 backend, dolphin crashes. (or from before a certain point, gives me error dialog boxes and then crashes)

What steps will reproduce the problem?

Open any game (I think, 3 games crashing in the same way from different regions makes me think it applies universally) and watch as dolphin crashes, as long as you have selected the direct3d11 backend.

It is important to make sure the bug hasn't already been fixed. Please tell us what the latest version you've verified the bug on.

5.0-5209 (latest as of August 19th at 5:00PM UTC-05:00 Eastern Time)

Is the issue present in the latest stable version?

No. Dolphin 5.0 (non developer release)

If the issue isn't present in the latest stable version, which is the first broken version?

There are 2 types of crashes I noticed while hunting for the first broken version. The first type of crash, starting on dolphin 4657, is that on starting any game the error is "Failed to initialize Direct3D. Make sure your video card supports at least D3D 10.0" and after clicking ok on that dialog box, a "Warning" dialog box says "Failed to create D3D device." and then dolphin crashes. This type of crash occurs for several releases. Starting on dolphin 4687, dolphin just crashes with no error dialog box. (i.e the "dolphin.exe has stopped working" dialog from windows itself appears with no messages from dolphin before that) This type of crash continues up to the current dev build, 5.0-5209.

If your issue is a graphical issue, please attach screenshots and record a three frame fifolog of the issue if possible. Screenshots showing what it is supposed to look like from either console or older builds of Dolphin will help too. For more information on how to use the fifoplayer, please check here: https://wiki.dolphin-emu.org/index.php?title=FifoPlayer

(This is not a graphical issue)

What are your PC specifications? (CPU, GPU, Operating System, more)

Pentium G3258 @ 4.0Ghz, GTX 760, Windows Embedded Standard 7 64 bit (it's just Windows 7 rebranded so this should not be an issue)

Is there anything else that can help developers narrow down the issue? (e.g. logs, screenshots,
configuration files, savefiles, savestates)

Note that the second crash references dxgi.dll while the first crash references dolphin itself. I combed through changelogs to find the ones pertaining to the versions that introduced crashes and did find something: https://github.com/dolphin-emu/dolphin/pull/5697 which is the pull request that became dolphin 5.0-4657, and there is someone else with the same issue, which leads to the pull request for 5.0-4687. (comment is from July 8) The pull request mentions that the proposed changes to the d3d11 backend would break its compatibility with Vista, but I am not using Vista (Windows NT 6.0 is Vista, Windows NT 6.1 is Win7/derivatives) and the proposed changes should not break anything. Here's the pull request that became 5.0-4687: https://github.com/dolphin-emu/dolphin/pull/5771 ironically this pull request was supposed to fix the aforementioned D3D initialization error but it breaks D3D even more for me. (and nobody that may have experienced the second crash I mentioned has reported it anywhere I looked)

If any other logs/info is required I will be glad to provide it.
