ByteString did not understand #asWin32WideString

CI on Win+P14 shows this error:

So, it seems LGitLibrary uniqueInstance libraryName produces this error in CI.

I see two possibilities:

• the environment variable has a special name or value that produces the error (but the log doesn't show which strings)
• UnifiedFFI, which is loaded as a dependency, removes asWin32WideString

In my Mac, in a Pharo 14, asWin32WideString exists as an extension of FFI-Kernel package... need to check on Win.
