What does the error "thread 1 received signal SIGTRAP, trace/breakpoint trap" signify?

edit

This error signifies that a trace or breakpoint trap was hit by Thread 1. This typically occurs when a program attempts to execute a breakpoint instruction, a debugging function has set a breakpoint, or a debugger is attached to the program and has halted execution at a specific point. It can also indicate an error in the program's code or a hardware issue.
