Fenix 7 Solar battery died just before race finish line, activity is not saved in my activities?

Please help. I did Bluetrail Tenerife 110km UTMB last week end and my Garmin Fenix 7 Solar died just before finish line. The activity does not seem to be saved anywhere in the watch or in Gamin Connect however all the steps, floors climbed, HR data all seem to be there but the actual race/activity is not. Please help, Is there anyway to find the activity within the watch via a laptop?? I will be gutted if it is lost. PLEASE HELP, MUCH APPRECIATED.
