Yes, in this case you are not (yet) in luck:

How to check  that:
--> Windows log files
    --> imagery/i.spec.unmix FAILED

Looking at the log file there, you will see
 main.c:31:2: error: #error GRASS is not configured with BLAS
 main.c:35:2: error: #error GRASS is not configured with LAPACK

That means, that the BLAS and LAPACK libraries are not present on the
Windows addons build server.

I found some here: https://icl.cs.utk.edu/lapack-for-windows/ but our
WinGRASS maintainer would need to install that (i.e. find the time and
have success with these libs).
Coming soon, I hope.

By chance we'll meet next week in Italy, I have taken liberty to add
it to the agenda:
