A factory reset brings you back to the default settings and removes all user created files (your pictures, assets, videos). Reinstalling the software or installing a new version doesn't do anything with these files.
From the top-right-corner menu, click on "Troubleshoot" and select the items you wish to reset
By creating a new Working Directory, you’re going to start with a fresh new set of files (settings, calibration, ordering, images/videos)
This is the preferred method if the software doesn't launch or if you are upgrading from a version that dates from 2019 or earlier.
The user files are located in c:\users\your-user-name\xangleCs
In the example below, my username is ROG3
To do a factory reset, you simply need to delete this folder. I usually suggest to keep a backup of these files in case you need to bring back the camera ordering files, the assets or the calibration files
This is going to create a whole new set of files with the default values
