I have been having the same issue for several days now. I only have one other game in the Epic Launcher but that starts the install as expected. There are multiple other people that I am aware of who are also having this problem with trying to install the Ark Dev Kit and others that have encountered problems when trying to verify files
The ‘fix’ that was mentioned earlier today in the Epic Games Twitter did not fix the problem we are all having with the MD-0011 error,
As well as seeing the same Install Failed message uploaded by Mayrin, I see this when I tried the troubleshooting in the launcher
