Check twice the encoder. In other post I wrote probably solution for this problem.

Hi, if You didn't solve the issue with the error, check the rotary encoder.
Desolder it from board, power up. If system boots in normal state - encoder is wrongly mounted.

The issue I have with one unit, desoldering the encoder solve the problem - was wrongly mounted on the small board.
