Expected behaviour

Julia kernel 1.6.2 (8 threads) starts

Actual behaviour

Kernel does not start

Steps to reproduce:

Create a 8 threads julia kernel with

using IJulia
installkernel("Julia_8_threads", env=Dict("JULIA_NUM_THREADS"=>"8"))

Jupyter: Create new blank notebook (from VSCODE) -> set kernel to Julia_8_threads.

The kernel does not start: Timed out waiting to get a heartbeat from kernel process. View Jupyter log for further details.
