Welcome Pratik Mondal,
I understand how frustrating it can be when you are unable to install any apps from the Microsoft Store and receive the message "There was a problem happening on our end."
Before suggesting further troubleshooting, could you please provide a bit more information:
- Are you signed in to the Microsoft Store with a Microsoft account or a local account?
- Does this happen with all apps or only specific apps?
Besides the earlier recommendations, you may find these additional options helpful:
Option 1: Run the Windows Store Apps troubleshooter.
- Open Settings > System > Troubleshoot > Other troubleshooters
- Run Windows Store Apps
Option 2: Reset the Microsoft Store cache.
- Press Windows + R
- Type wsreset.exe
- Press Enter
- Wait for the Store to reopen automatically
Option 3: Repair and reset Microsoft Store.
- Open Settings > Apps > Installed apps
- Select Microsoft Store > Advanced options
- Click Repair
- If the issue persists, click Reset
Option 4: Re-register Microsoft Store.
- Open Windows Terminal (Admin)
- Run:
Get-AppxPackage -allusers Microsoft.WindowsStore | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppxManifest.xml"}
I hope this helps. Please let me know the results of the above tests, and I will do my best to assist further.
