Error evaluating 'gcode_macro INITIAL_FRONTEND_UPDATE:gcode

Hello again. I update my printer to RatOS 2.1. Sometimes when startup my printer, i see this red warning. Whats this?
The same mystic undervolt warning for my Rasberry. Not ever. The voltage is 5.23V. This warning appears only in RatOS 2.1. Not in the last two years i used 1.9.
