unable to build a seahorse project

[wardady06]

calculator git:(master) ✗ seahorse build
✗ Compiling calculator... (note: if this is your first time building, it might take a few minutes)
Error: anchor build -p calculator failed:

This is most likely a bug in the Seahorse compiler!

If you want to help the project, you can report this:

• as a Github issue (https://github.com/solana-developers/seahorse/issues).

Thanks!
