Board: NodeMCU ESP-32S

Description:

For a school project I need to control 8 segments of the MAX7219 using the LEDControl library. A half year ago when I paused the project everything worked but two days ago when I started again, it did nothing. After uploading the sketch the matrix lights completely up (every pixel) but when I replug it into my computer nothing happens. But the same works perfectly when I use an Arduino Uno. The debug message is the same as when I upload other sketches. I tried reinstalling the Arduino IDE and both ways (Board Manager and git GUI) of installing the Arduino Core, also the avr/pgmspace.h fix. I tried different Pin configurations (GPIO Pin 4, 2, 0 (used back in the days) and 13, 10, 9). Everything with no success.

I say thank you in advance for your time.
Yours sincerely
Stephan P.

Sketch: (It's unnecessary, it should just show that controlling isn't possible, thanks to Brainy Bits for their sketch)
