Crew package does not work with vscode-R

Describe the bug
When using package crew in vscode-R, local workers do not start. I have not tried remote workers. crew is now the preferred method for high-performance computing for the targets package so this will affect quite a lot of people.

To Reproduce
I can reliably reproduce this using a slightly modified example from crew's introduction vignette:

library(crew)
controller <- crew_controller_local(
  name = "example",
  workers = 2,
  seconds_idle = 10
)
controller$start()
controller$push(name = "get pid", command = ps::ps_pid())
Sys.sleep(1)
controller$pop()

The last statement should return information on the spawned workers, instead it returns NULL.

Running another example from the vignette leads to nonsensical output because no workers are started:

results <- controller$map(
  command = a + b + c + d,
  iterate = list(
    a = c(1, 3),
    b = c(2, 4)
  ),
  data = list(c = 5),
  globals = list(d = 6)
)

# -1 of 2 tasks done (-50%)

This happens every time when using vscode-R, both with a radian console and a vanilla terminal, but not in radian or a vanilla terminal outside of vscode-R, and not in RStudio.

Can you fix this issue by yourself? (We appreciate the help)

No

Environment (please complete the following information):

• OS: macOS 13.6.2
• VSCode Version: 1.84.2
• R Version: 4.3.2
• vscode-R version: 2.8.2
• crew version: 0.6.0
• mirai version: 0.11.0

Start by reproducing the crew_controller_local example in vscode-R using the reported macOS, VS Code, R, vscode-R, crew, and mirai versions. Compare it with the same example outside VS Code; done means local workers start and controller$pop() returns worker information instead of NULL.
