Vowen 0.4.3 on Windows won't start

Vowen 0.4.3 on Windows starts and immediately exits with no visible UI unless launched with SwiftShader flags.

Normal launch reaches app initialization but Chromium/Electron GPU process crashes repeatedly, then exits with: GPU process exited unexpectedly: exit_code=-2147483645 FATAL: content\browser\gpu\gpu_data_manager_impl_private.cc:415 GPU process isn't usable. Goodbye.

Workaround that makes it launch: Vowen.exe --use-gl=swiftshader --use-angle=swiftshader --disable-gpu-sandbox

Plain --disable-gpu did not fix it. The app works with SwiftShader.
