New to 3D : warning-key-2401-unknown-exception/4877

hello to all this is my first day.
I printed the boat (gcode) with the USB fine. Then tried to print other files in .STL and did not work. Also tried to print from clous on Android and print stops with an error code: warning-key-2401-unknown-exception/4877
Also tried to print with LAN Creality Print 5.0 and it recognized the printer perfectly, but the print stops with the same error.
Can you help me? Thanks
