This library is very good for his lightweight and reliability but in every sketch, with any kind of library or without libraries, that occupies more than 39% of dynamic memory... it doesn't work!
Error code 128
I found this in 'SimpleSDAudio.h' with the corresponding hex error code
#define SSDA_ERROR_NULL 0x80 // Null pointer
What does it means?
Where is the offending line in the .h file?

This library
Post a link to where you got the library from. Please use the chain links icon on the toolbar to make it clickable. Or if you installed it using Library Manger (Sketch > Include Library > Manage Libraries) then say so and state the full name of the library.

Keep in mind the 39% is only the dynamic memory used by globals in your code. You also need enough dynamic memory for local usage.

Where do you encounter that error?

It means the macro SSDA_ERROR_NULL is defined as 0x80.

The error code is returned by a method in the code and it can be printed in Serial.
I know that that is a definition, I didn't understand what does 'Null pointer' means so we can find what's the problem in this library.
The Arduino is a microcontroller. It is not a media player. If you want to play audio, use dedicated hardware.

The code means malloc failed. You don't have enough RAM. Checkout the method SDPlayClass::init() in
SimpleSDAudio.cpp

Please be constructive, not churlish.

Trying forcing some checks in that file.
But I'm thinking... the program won't work anymore because there isn't enough phisical space.
So... in my opinion, I can do nothing
