Garmin Forerunner 935 GPS distance is way off

I used the watch beginning of March and then I didn't had any activity for 2-3 weeks. Last week I started to use the watch again for running and after workout noticed that recorded distance is way off. Usually my running lap is ~7,4 km and now it shows 10,5-11 km. My watch is having latest SW version.  I did try this, suggested in other topic:

"You might be having an issue with the CPE file on the watch. This can sometimes happen if the watch hasn't locked on to GPS in awhile, causing the watch to not acquire satellites. You can try the following steps and usually it will resolve the issue. 

  • Plug the watch into a computer
  • Access the device drive
    • Windows 
      • Connect the Garmin device to the computer 
      • Press the Windows key + E on the keyboard to open Windows Explorer/File Explorer
      • Select This PC (Windows 10 only)
      • Open the Garmin drive listed
    • Mac
      • Connect the Garmin device to the computer
      • Open Finder
      • Select Go in the menu bar at the top of the screen
      • Select Computer
  • Open the Garmin Folder
  • Right Click on the Remote SW folder and delete it
  • Sync with Garmin Express "

But it didn't helped me. Does anyone have similar issues and can suggest something what could fix it?
