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

• Plugin install via npm fails behind proxy with 'fetch() proxy.url must be a non-empty string' #21098: Same error message (fetch() proxy.url must be a non-empty string) during plugin installation via npm — the root cause appears to be the same proxy handling bug in OpenCode's plugin install path, even though your issue occurs with proxy disabled (Windows) vs. proxy env vars set (Linux/WSL).
