Hi, We will release version 3.9.6 recently (about two weeks ) to fix the ESP32-C2 encryption problem. You can refer to the latest documentation for operation.

Interim, you may use the IDF tools for enabling flash encryption on ESP32-C2. Please refer to this guide https://docs.espressif.com/projects/esp-idf/en/latest/esp32c2/security/host-based-security-workflows.html#enable-flash-encryption-externally for externally generated flash encryption key workflow.

I will close this issue for now.
