Black screen on launch (Windows 11)

[Youp3]

Describe the bug
When I launch Kudu on Windows 11, I only have a black Window at the second attempt. I think it is similar to the issue #148

To Reproduce
Steps to reproduce the behavior:

1. Kudu is installed in "C:\Program Files\Kudu"
2. Click on Kudu shortcut on Desktop and validate the privilege elevation request. Nothing appears.
3. Click on Kudu shortcut on Desktop and validate the privilege elevation request. A black window appears, without icon to close or reduce it.

Expected behavior
Just have the Kudu window displayed.

System Info

• OS: Windows 11 25H2 up to date
• Version 1.48.0

Additional context
Regarding points of the #148:
2/ Powershell result for & 'C:\Program Files\Kudu\Kudu.exe':

3/ Nothing in the Windows Event Viewer.
4/ Nothing more than the black window.
5/ app.asar file is in C:\Program Files\Kudu\resources
6/ No change
7/ No change

In kudu.log file, I have these lines:
[2026-08-08T16:15:57.181Z] INFO: Scheduler started
[2026-08-08T16:15:57.415Z] ERROR: Renderer process gone: reason=launch-failed exitCode=18

Maybe a latest thing: my gpu is an AMD Radeon RX 9070 XT

And maybe the result with --disable-gpu --disable-software-rasterizer in Powershell:

& 'C:\Program Files\Kudu\Kudu.exe' --disable-gpu --disable-software-rasterizer
