We'd mostly be guessing here, use strace or https://learn.microsoft.com/en-us/sysinternals/downloads/procmon to see which path is actually being accessed and why it failed. Also check that you can run `as` correctly. This error can also happen if a dependency of `as.exe` isn't found during loading.
