What should I do if KDX freezes when trying to delete the data folder?

If KDX freezes on the 'Delete Data Folder' button, exit KDX completely and delete the data folder manually. This happens because kaspad (the Kaspa node software) can hang during an upgrade, and when KDX tries to stop it in order to delete the folder, KDX itself gets stuck waiting. The fix is straightforward: close KDX entirely, then navigate to your home folder and find the hidden folder called .kdx — inside it is a subfolder named data, and that is the one to delete. On Windows the path looks like %userprofile%\.kdx\data; on Mac or Linux the .kdx folder is hidden by default, so on macOS Finder press Command+Shift+Period to reveal hidden folders. Knowing this workaround saves you from being stuck with a frozen application and lets you get KDX back up and running without reinstalling.
