Launcher may leave zombie processes running that prevent upgrading
Upon launching the Minecraft Dungeons launcher this evening (6/3/20) it attempted to update but failed with the pictured error message ("Unable to update the Minecraft Dungeons Native Launcher"). Clicking the "OK" button on this dialog terminates the launcher. After retrying an additional time, I checked the Windows task manager and noticed that two Minecraft Dungeons Launcher processes had been left running as zombies from previous times I had closed the launcher. Terminating these zombie processes allowed the update to continue normally.

Are there any zombie processes in Task Manager? If so, does terminating them solve the problem (MCD-2985)?
