Emulator

Game Name?

Affects all games, and also fifologs.

What's the problem? Describe what went wrong.

If you open the graphics settings window immediately after launching a game (or starting to replay a fifolog), Dolphin will crash. This has happened to me by accident several times, since I often need to change graphics settings to test something, but probably doesn't affect most end-users. I've confirmed that this happens with Vulkan, but it may affect other backends as well.

What steps will reproduce the problem?

1. Start Dolphin.
2. Change the graphics backend to Vulkan.
3. Close and reopen Dolphin (this may not be required, but seems to help with consistency for me).
4. Select a game in the games list.
5. Move the mouse over the graphics settings button.
6. Press enter to launch the game, and then immediately click on the graphics settings button.
7. Dolphin will crash.

Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.

Yes, 2409-45 (built from source).

Is the issue present in the latest release? For future reference, please also write down the version number of the latest release.

Yes, 2409 (prebuilt).

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

• CPU: Intel(R) Core(TM) i7-10750H CPU @ 2.60GHz, 2592 Mhz, 6 Core(s), 12 Logical Processor(s)
• GPU: NVIDIA GeForce GTX 1650 Ti; also affects integrated Intel GPU
• OS: Windows 10 Home 10.0.19045.4894

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

I'm pretty sure this happens because the graphics settings attempts to load Vulkan if it's not already loaded, and then unloads it afterwards. This results in it being unloaded while the game is trying to use it. Here are a few stack traces:
