Hi, thank you for reaching out. I’m happy to help.
Does this error appear when you install any app or just a specific app?
- If you're using a VPN or Third-party antivirus program, try temporarily uninstalling it to see if the problem goes away.
- Try resetting the MS store cache.
Press Windows + R then type 'wsreset.exe -i' (without the quotes)
Hit Ok, wait 10 seconds then try to check again.
