I ran a debug build on master 0c23a2c and also in beta2.
This can be considered partially fixed, since after few seconds on white screen, the splash screen was seen for few seconds.

Edited: So splash screen works now but it's just slow. We can update the issue title maybe.

OS: Window 11 Pro 22H2 64 bit

GPU: AMD RX 570(4GB version)

Yep, the splash displays, but the white window looks rather bad. It shouldn't show window at all until it loads. Or at least use the default clear color...
