I have the same issue on "original" chinise firmware too
some hardware issue - mcu maybe cannot talk to ds1302
usually missing pullup/pulldown, or problem with clock/data lines.
maybe problem during assembly - recheck schematics, soldering, etc.

Yes, it was HW issue.
DS1302 should have some capacitance on Vcc and Vbat pin, otherwise it resets during switch.
No software issues, closing.
