Trying to import Goteborgsvarvet track but Connect says something is wrong with the file.

No idea what was wrong with it. I got the same error.
I uploaded it to Strava and then exported it as a GPX and now it works to import into Garmin Connect: Göteborgsvarvet 2023.zip
Great, works for me as well. Thanks a million for your help!
