Hi Clay! Thank you so much for this report :). You are correct of course, in that your path with the accented character is what is causing an issue finding the projects in the Launcher. I have added this problem to our bug tracking software so that we can get it sorted.
Hopefully a workaround for you, rather than format your computer

You can change where projects are installed to using the link on the marketplace download page. This will set a new default. If you can work with that for the time being, hopefully we can fix this soon.
Thanks,
Leigh
