The latest btchip-python release contained a malformed dependency that used to be treated as a warning, but is now treated as an error by recent pip version. And even with the slightly older versions of pip currently used in release scripts we already get an error the Windows build, because there is an additional step (compared with the linux appimage build) that already treats this as an error.

It seems like btchip-python is no longer maintained by Ledger, and the proposed fix in https://github.com/LedgerHQ/btchip-python/pull/54 is not going to be merged and released.
