After the update, the esp32C3 cannot be used with the USB upload program anymore

After the Espressf 32 version was updated from 6.4.0 to 6.7.0, I used USB to upload the program once, and ESP32c3 can no longer use USB, Using the flash_download_tool_1.9.5 tool also prevents the program from being uploaded or cleared, Ensure that there are no issues with the hardware and program, and that they have been working normally for a long time in 6.4.0, Switching back to 6.4.0 also prevents the use of USB upload programs.

Known bug in Arduino Core 2.0.16 Is fixed in Core 2.0.17 You can use with

platform_packages = framework-arduinoespressif32 @ https://github.com/espressif/arduino-esp32/releases/download/2.0.17/esp32-2.0.17.zip

until Platformio release the core 2.0.17

Thanks, but is there any way to fix the locked ESP32C3?

It can be fixed by downloading via serial port. Connect GPIO8 to high level and enter download mode manually.
