I have submitted a fix for this in PR #718. It improves the error logging for the deploy command and makes the process execution more robust against encoding issues to prevent silent failures.

[iice257]

Submitted PR #720 with a focused fix: the deploy command now includes captured subprocess output in the error raised for non-zero exits, and the existing bad-exit approval snapshot covers the behavior. Verification: python -m pytest tests/project/deploy/test_deploy.py::test_command_bad_exit_code -q and python -m ruff check src/algokit/cli/project/deploy.py tests/project/deploy/test_deploy.py.
