Lost Data - Computer Crash

My iMac apparently crashed as I was about 45 minutes into a one hour workout session.  The portion of the ride I completed does appear on my computer’s Zwift dashboard, but did not upload into Strava.  Attempting to manually upload the data was unsuccessful with a message indicating the file was malformed.  Will my elevation gain and calories burned be added into my Everest and Holiday challenges? Anyway to fix the corrupt file?

Thank you

Run the .fit file through the Corrupt Time Fixer hopefully it will then upload to Strava
