The board uses a tiny 26MHz crystal (X1) and a 32.768kHz RTC crystal (X2). The note from the schematics: The WLX896B will not start if the 32.768kHz crystal is missing even if the main 26MHz is present. This is because the PMIC uses the low-speed clock for its power sequencing FSM.
Ensure adequate thermal interface material (TIM) or thermal pads are applied beneath the PCB where heavy copper planes dissipate heat. Troubleshooting and Repair Guide wlx896b schematic exclusive
