Used Chrome & Edge as browser. Progress bar stucks at 99%.
Any ideas?
Thank you.

@SideFx Thank you for reporting this. Please open the Chrome developer tools / inspector / console and copy any error message you see in the console here (there should probably be a panic and a stack trace). Please also go to chrome://gpu, click Download Report to File, and then upload the resulting file here. Thank you!

Thanks for the quick response, I did as suggested, here's the error log:

And here's the GPU log:

@SideFx Thank you for providing that debug information. The GPU device report states that WebGPU is not supported on Windows arm devices, so the solution to this is to correctly use the backup 2D drawer when WebGPU isn't supported but is declared as such (browsers provide a navigator.gpu field even when they don't support WebGPU in cases like this, so we need a more advanced fallback procedure). We have been meaning to do this before and it shouldn't be too hard to implement. This should also fix issues with other browsers such as Firefox Nightly, Brave, Kiwi Browser, and Linux browsers, as we can now have a robust WebGPU enabling rule instead of a limited heuristic. We will fix this as soon as possible. See also the more long-term #1144.
