Invaild JSON String (Xbox app Windows 10)

what do you replace that part with in the path?

I now have done everything but it is still giving me the error (sorry for the late reply i was away for the weekend)

You can use the Disk Cleanup tool to delete temporary files and system files from your device:

1. In the search box on the taskbar, type disk cleanup, then select itfrom the results.
   
2. Select the check box next to the type of files you want to delete. (To view a description of each type of file, select the name.) By default, Downloaded Program Files, Temporary Internet Files, and Thumbnails are selected. Be sure to clear those check boxes if you don't want to delete those files.
   
3. To free up even more space, select Clean up system files, and then select the type of system files you want to delete. Disk Cleanup will take a few moments to calculate the amount of space that can be freed up.
   
   Note: If it’s been fewer than 10 days since you upgraded to Windows 10, your previous version of Windows will be listed as a system file you can delete. If you need to free up drive space, you can delete it, but keep in mind that you'll be deleting your Windows.old folder, which contains files that give you the option to go back to your previous version of Windows. If you delete your previous version of Windows, this can't be undone. (You won't be able to go back to your previous version of Windows.)
   
4. After you’ve selected the types of files you want to delete, select OK, and then select Delete files in the confirmation window to start the cleanup.
   

Furthermore, you can use an external storage device to help you complete the update. To learn more, see Free up space to install the latest Windows 10 update.
