We can help 
Please zip the fit file then attach it to this thread - Insert > Image/video/file > upload.
This should work for you - 2021-01-23-11-15-09-fixed.fit
You can unzip the file and upload using Garmin Connect Web, import data.
This was automatically repaired using Fit File Repair Tool.
Of note was the erratic elevation data “unexpected big change of altitude value.” Let me know if you want that fixed as well. Would need to manually enter the correct altitude data for those timestamps.
Also, there was no device info, so I changed it to the Edge 820 and added a dummy serial number.
