I've tried to upload my "invalid" activity from today,, and getting an error It's a FIT file, so wondering if it's corrupt and how I can get it fixed and uploaded.

Assume you've already tried this? - How Do I Manually Upload an Activity I Recorded to Garmin Connect?
If so, and you're getting errors, you can try to repair the file using 3rd-party tools, such as FIT File Viewer. Runs in the browser and requires no additional software. If you're still unable to import the activity into Garmin Connect, attach the file to this thread. We can take a look to see if it is repairable.
