Close as is mentioned in https://github.com/bevyengine/bevy/issues/140#issuecomment-683379069

Even if your gpu doesn't support DX12/Vulkan, we still should not segfault, just return no acceptable adapters. Having a backtrace of the segfault would be useful.

Would you be able to test on current master to see if the issue still occurs for you?

Sorry for the late replying. My old laptop, which caused this issue, has been broken for a long time and I can't find a trusted engineer to fix it, so I have no environment to reproduce this issue.

No worries, I'm going to close the issue for now, but if you can reproduce it, feel free to re-open the issue or file a new one! Best of luck getting it fixed.
