Good point, let's get a backtrace.

OK fine let's run the full backtrace out into a file. Surely the program won't completely skip STDERR and STDOUT!

Just kidding, it absolutely does skip STDERR and STDOUT 🤦‍♂️ .

Looks like it's trying and failing to use the Nvidia GPU instead of the integrated Intel chip. Dual GPU setups are always weird, but I just updated the dev branch to support the environment variables listed here: https://crates.io/crates/wgpu

On the latest dev, try setting WGPU_ADAPTER_NAME to Intel(R) UHD Graphics (CML GT2) so that the Intel adapter is preferred.
If it still doesn't work, see if you can get the examples in the wgpu repo to work: https://github.com/gfx-rs/wgpu/wiki/Running-the-examples
