I'm trying to get MCD to boot on my Windows machine and it seems to spin up the process but then no window appears even after leaving it for a time (procedure below).

I've also noticed that opening and closing the launcher and trying to open MCD via its exe file leads to multiple Minecraft Dungeon/Launcher processes continuing running for no reason.

Procedure:

• Download the launcher
• Let it update, it appears to update to 2.1.14931
• Install Minecraft Dungeons to a non-default location
• After download completion click Play
• Wait for MCD to boot
