Please trim your message. Your log is very long because you have included 5 failed launch attempts that all look pretty much the same.
The problem appears to be that the itch app is not able to find any executables. Maybe something went wrong when installing Tiled. In that case please try deinstalling _all versions_ of Tiled (also make sure no Tiled is mentioned in the "Add/Remove Software" Windows settings panel), and then install Tiled again.
