You can't update anything including the store if you can't load downloads.

My Microsoft Store app keeps suddenly freezing and crashing when going to any tab on this page (mouse input disabled once it attempts to load also). Multiple reports indicate a few problems with the Microsoft Store, such as frozen window, endless loading, and the inability to download apps. However, the app store seems to be suffering an outage for the past several hours. Just like the Google Android Play Store or Apple iOS App Store, the apps receive OTA updates regularly. Microsoft has been urging Windows 10 users to change their habits and head over to the app store to download apps. Windows 10 users are currently experiencing issues with the Microsoft Store, with the app unable to download and install apps and crashing after repeated attempts. Microsoft Store is crashing worldwide on Windows 10 PCs While this may seem risky, there are several trusted sources to download genuine applications and programs for Windows 10. Windows PC owners have the freedom to download and install apps from any location.
