Hi
You could try these methods:
Please make sure your Windows has the latest update, and try updating the Microsoft Store:
Microsoft Store>Download & updates> Get updates
Also please check if you are signed into the Microsoft Store with your Microsoft account.
If these doesn’t work, try resetting Windows Store cache through Command Prompt
Run Command Prompt as administrator
Type wsreset.exe and click enter
Reboot your computer
I hope this information above can help you.
