I have a DRV8833 MJKDZ with 12 pins and I try to run a 2.5 - 6V motor with it, using PWM with a Pi Pico, and it also worked once and back then the only problem was that when there was too much load on the motor the LED on everything turned off as here.
But now, after changing nothing just leaving it in a corner for a month or so it doesn't works at all. The first thing that can happen is that the LEDs stay on but the Motor doesn't move at all or only vibrated minimally and if I try to start it by rotating it, it sometimes powers for half a second but then stops again. The second thing that can happen is, that the LEDs on the Pi Pico and on the DRV8833 just turns off and then back on as soon as I disconnect the motor.
Now I can power the motor by using the 5V from the Pi Pico that also runs into the GND and VCC from the DR8833.
What's the problem and how can I solve it?
P.S.:I am powering the DRV8833 using the 5V sys power from the Pi Pico and powering the Pi Pico form a USB Port of my PC and the J2 Jumper is connected, as it worked once.

The load only whats attached to it on the picture.
I don´t know what kind of motor I have as the label isn´t readable except for the 2.5 - 6v, but here is a picture:
