There's a datasheet for the SW6106 PMIC that let the magic smoke out here: https://www.waveshare.com/w/upload/e/ed/SW6106_Datasheet_Release_DS008_v1.0.pdf

You can check if component values match the reference design and if your usage was pushing it too close to its rated limits.

Note:
When Using More Than 2 Output Ports at the Same Time, The Fast Charge is Triggered By Mistake, All are 5V Output

Not sure what they mean by "triggered by mistake" whether all the outputs are limited to 5v when more than one port is drawing power.
