Unable to execute programs in GDB as permission denied

[D31ty]

In my Mac M1, I installed Lima and started the server by following these steps:
https://stackoverflow.com/questions/75672471/installing-gdb-on-my-apple-macbook-m1-2020?noredirect=1&lq=1

I modified the ~/.lima/default/lima.yaml, as suggested such that I can edit and run the programs.

My Scenario:
I wanted to decompile a file from Pico CTF challenge, where a Linux executable file was given
File type mentioned below:
root@lima-default:/Users//Downloads# file debugger0_b
debugger0_b: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, BuildID[sha1]=95b0203be2982e75dbc01d1cc25b1309f7aec5f7, for GNU/Linux 3.2.0, not stripped

When I run the "run" command inside the gdb, I get this error:
/bin/bash: line 1: /Users//Downloads/debugger0_b: Permission denied
/bin/bash: line 1: exec: /Users//Downloads/debugger0_b: cannot execute: Permission denied

Help on this issue.
