I can reproduce this bug, too with the same log lines.

@burmancomp , @irrah68, @zstanecic, I believe I have resolved this in #17513. If you're comfortable doing so, would you mind testing either from source or with the launcher once the AppVeyor build completes?

[zstanecic]

@SaschaCowley will test from source now. it is fater to build.

[zstanecic]

@SaschaCowley The I confirm that the sapi5 now loads properly.
