Missing syntax highlighting for python and rust

[LoadingBG]

Summary

I updated from version 24.03 to version 25.01. Now the syntax highlighting is broken for python and rust.


Diagnostics still work and are highlighted properly. I haven't found other languages with broken highlighting.

The same issue occurred on version 24.07. I reverted back to 24.03 and everything was fine.

Reproduction Steps

I used scoop update helix. After that python and rust files lost highlighting.

Have you ran hx -g fetch and hx -g build?

I completely forgot about grammar building. Looks like everything is fine now except for python. It fails to build but I guess this will be resolved by the python grammar repo.
