I cant upload activity on Garmin or Strava

Hello. Recently I did 29 days hike activity. I used ,,resume later,, tab every night on my Garmin Instinct Solar Tactical After 19 days I couldnt continue with activity because watch said ,,The storage is full,,. So I saved activity and started a new one (I wanted to use some tool later to put them into one activity). After finnish and saving of my second activity I couldnt find the first one. Watches deleted it on their own..... I googled a lot and find a recovery tool and now I have the first part of my hike. The problem is, I cant upload it to Garmin or Strava because it says: ,,We dont support the file type you tried to import,, Can someone help? I tried repairing tools but nothing helped.... Here is the file.https://easyupload.io/n8mwhq Thanks for help
