Hey @janek515, thanks for reporting this and for submitting a fix! I’m able to reproduce this issue. I tried creating a new user on Windows with a space in the username, and when starting the emulators an error was raised. Let me raise this to our engineering team so they can take a look into the issue as well as the PR.
