Interrupt fails on Windows/Juno - enabling powershell does not help

When I attempt to interrupt Julia in Juno on Windows, i get the message

“Uncaught Error: Signals not supported on windows”, and
“The error was thrown from the julia-client package. This issue has already been reported.” → link alerting me to enable the powershell.

Enabling powershell does not resolve the issue though. Any suggestions?
