Wemos D1 pro allways reset by pressing a button

Hi @ all
I’ve a strange issue and i didn’t find a solution till now. Hope someone here can help me.
I use a Wemos D1 pro and WS2812b for a WLED-Project. Everything works fine.
But i also need some phisical buttons.
Everytime i push a button, phisical or touch (TTP223), the Wemos/WLED does a complete “factory reset”. All configs i’fe done are back on stock (including network!).
I’ve tried the same setup with an Wemos D1 mini, same issue.

Did anyone have an idea?

Thx

Long press (>10s) will trigger factory reset.
