My first guess is that GPU passthrough either isn't available (CPU fall-back?) or is throttled.
Please be more specific and explain how you're running it, though.

I thought the same! For some reason it worked before yesterday, I restarted my PC today and got this. I suspect something is wrong with my wsl instance (not sure - I haven't made any changes since yesterday). For context other tasks requiring the GPU to work are fine e.g. running machine learning models with PyTorch, nvidia-smi output is fine, nvcc is there

No idea! I also don't use Linux.
Maybe @armansito or @DJMcNab would. Looks like, although perhaps unrelated, some strange parsing of the shaders.
Particularly standing out:

Those messages (about the #endif directives) are harmless; the WGSL preprocessor doesn't gracefully handle inline comments that follow an #endif directive and print out this error message. I'll send a PR to suppress those so they don't spam the logs.
