Emilgardis commented

Could you try uninstalling stable-x86_64-unknown-linux-gnu then reinstall it

soruh commented

That seems to have worked. It now works for both architectures.

Thanks a lot!

Emilgardis commented

Awesome! We actually have a warning for a similar issue, but I think this one is pretty much impossible to detect reliably.
