[BUG] Garmin fr255 version 15.19 crashing loading course navigation.

Question

Every time I load a running course and select navigation, the device crashes and reboots. This problem persists with multiple courses. However, courses still work without problem on cycling activities.

I had my fr255 Music freeze for several years now, when trying to load courses (it froze before even seeing the course list). Recreated by doing this: Start button > Run > up button menu > Navigation >Courses ->> FREEZE. I think I might have solved the issue: Connected the Fr255 music to computer. Entered the watch via Explorer in Windows 10. Moved all the files inside the folder "Courses", to a backup folder on my computer. (internal storage > GARMIN > Courses). 
 Now the watch didnt freeze anymore. So it seems one of the courses (.fit-files) loaded on the watch was the source of the problem. Now, there was 1 of 14 files that had much bigger file size than the others. It was 60 kB big, while the other files was between 1-10kB. I tried loading one file at a time, and when this 60kB file was loaded inside the watch folder, the watch deleted it automatically. So it seems the watch did a clean up on that file. The other 13 .fit-files are now inside the watch again, and I can FINALLY run using Courses!
