What's the problem? Describe what went wrong.

Issue n°1:
With Vulkan selected, Dolphin will crash instantly when loading the GameCube BIOS, either for the main menu or for the startup animation. Works by bypassing the animation (selecting the "bypass main menu" option) or using other rendering engine (Direct3D 11 for example).

Issue n°2:
On some games (at least the two TimeSplitters), with Vulkan selected, an infinite loop of error message "Failed to send command buffer" will show up during the initial game loading. Does not show up with another rendering engine as well.

What steps will reproduce the problem?

Both issues can only be reproduced with Vulkan selected.
Starting with build 5968, start the GameCube main menu or enable the startup animation for the first issue.
For the second issue, start one of the two TimeSplitters games without the startup animation and wait the game to fully loads.

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: Build 6105

Is the issue present in the latest stable version?

No (as Vulkan is not supported on version 5.0 stable).

If the issue isn't present in the latest stable version, which is the first broken version? (You can find the first broken version by bisecting. Windows users can use the tool https://forums.dolphin-emu.org/Thread-green-notice-development-thread-unofficial-dolphin-bisection-tool-for-finding-broken-builds and anyone who is building Dolphin on their own can use git bisect.)

Build 5968 (as stated there: https://forums.dolphin-emu.org/Thread-build-5968-new-issues-with-vulkan)
