Thank you for posting your question in the Microsoft Q&A forum.
Regarding your issue, switching out of S mode relies entirely on the Microsoft Store activation service. When the Store cache, sign‑in state, or required services aren’t responding correctly, the Store shows that generic error instead of completing the switch.
Here are a few steps you can try:
- Reset the Microsoft Store Cache
- Press the Windows Key + R on your keyboard.
- Type wsreset.exe and hit Enter.
- A blank black window will pop up. Don't close it. It will automatically close itself and reopen the Store once the reset is finished.
- Try the switch again immediately after.
- Check the "Windows Update" Service
- Type Services in your search bar and open the app.
- Scroll down to find Windows Update.
- Right-click it and select Restart. (If it’s stopped, click Start).
- Do the same for the Background Intelligent Transfer Service (BITS).
- Clear "SoftwareDistribution" Folder
- Search for Command Prompt, right-click it, and Run as Administrator.
- Type net stop wuauserv and hit Enter.
- Type net stop bits and hit Enter.
- Open File Explorer and go to C:\Windows\SoftwareDistribution. Delete everything inside this folder.
- Go back to the Command Prompt and type net start wuauserv then net start bits
