Hello,
Thank you for all the details and the troubleshooting steps that you've provided. Since the troubleshooter found an issue with the Windows Store Cache, we suggest that you reset the cache folder in App Directory. Kindly follow the troubleshooting steps below:
- Open File Explorer, copy paste the following path in the explorer address bar and press Enter. Kindly change the <username> with the username associated with your account.: C:\Users<username>\AppData\Local\Packages\Microsoft.WindowsStore_8wekyb3d8bbwe\LocalState
- In the LocalState folder, check whether the cache folder is present or not. If the folder is present, rename it cache.old. After that, create a new folder and name it cache. In case the cache folder is not there by default, just create an empty new folder and name it cache.
- Close the File Explorer and reboot your system. After the reboot, run the Windows Store Apps troubleshooter again. This time it will not only detect the problem but also automatically resolve it.
Please let us know the results.
