CrowPI 3 - Module issues

Hello Elecrow Community,
I just received my CrowPi3 (Kickstarter version), and while it looks like a great product, I’m running into issues with the modules:
Issues:
* Non-functional modules:
* Buzzer: No sound output (even with basic example scripts).
* LED: Python error: 121 Remote I/O error when running test code.

Abnormal I2C scan:
Only one device detected (0x13)—shouldn’t there be multiple?
Commands tested: sudo i2cdetect -y 1 and sudo i2cdetect -y 0 (no change).

No startup animations:

Unlike demo videos, no modules light up (LED matrix, LCD, etc.) after Pi reboot.

Troubleshooting steps:
✅ Enabled I2C via raspi-config.
✅ Tested official examples (no success).
✅ Verified all physical connections (everything seems plugged in correctly).

Questions:
Did I miss an initialization step?
Could this be a hardware defect or a software/config issue?
Is there a factory reset procedure for the modules?

My setup:

CrowPi3 (Kickstarter edition)
Raspberry Pi (built-in, OS updated)
Python 3.11.2 (no update after reception CrowPI)

Thanks
