Start Steam validating game files stuck at 100

Steam validating game files stuck at 100

This is due to the use of an older version of the launcher that is no longer supported.

It instead goes to try validate the steam/tf2 cache, but once it reaches 100% it just does nothing and hangs.

Closing it out and trying to launch again just results in the validation screen coming back up.
