Forerunner 955 Watch Activity Will Not Sync

Hi all, 

Recently completed a triathlon, and my watch will not sync my activity to my Garmin Connect App even though I can see the activity on my watch. When trying a manual upload it says "We do not support the file type you tried to import" even though it is a .fit file. Can anyone fix this file or have any advise? I attached the link to the file below. Thank you in advance
