This issue might be a duplicate of existing issues. Please check:
Both issues are related to the same root cause: unsigned Bun-generated DLL files triggering Windows security warnings. Feel free to ignore if your specific case differs from these.

this is a false alarm but we will get code signing to fix it
Hona commentedon Mar 29, 2026
As of OpenCode v1.3.4 across the CLI + Desktop apps, we have full code signing - so there should be no more warnings.
Please let me know otherwise
