What steps will reproduce the bug?

$ node inspect -e "const a = 1"
debug> c
debug> list()

How often does it reproduce? Is there a required condition?

No response

What is the expected behavior?

Debugger should throw ERR_DEBUGGER_ERROR just like sb() command since the runtime context has been already destroyed.

debug> list()
> 1 const a = 1
debug> c
< Waiting for the debugger to disconnect...
< 
debug> list()
node:internal/debugger/inspect_repl:362
      throw new ERR_DEBUGGER_ERROR('Requires execution to be paused');
      ^
debug> sb(1)
node:internal/debugger/inspect_repl:362
      throw new ERR_DEBUGGER_ERROR('Requires execution to be paused');
      ^

What do you see instead?

debug> list()
> 1 const a = 1
debug> c
< Waiting for the debugger to disconnect...
< 
debug> list()
node:internal/debugger/inspect_repl:638
    return selectedFrame.list(delta).then(null, (error) => {
                         ^
