This issue might be a duplicate of existing issues. Please check:

  • #1635: Similar ProviderInitError with full-screen display when using a different provider (Anthropic)
  • #2950: Identical ProviderInitError on Apple Silicon Mac with same macOS version (26.0.1), also occurs immediately when sending first message
  • #352: Provider initialization issues with model selection problems

Feel free to ignore if none of these address your specific case.

@JIbald that definitely shouldn't happen, can u run: opencode run hello --print-logs

Maybe add the --model anthropic/claude-sonnet-4-5 flag depending on default / last used model
