Dear SimonShin1,I understand you are getting the Runtime broker error;
Initially I recommend that you do the following;
Press Windows key + I and access Accounts;
Click on input options;
In privacy disable the option 'Use my login information to automatically complete my device settings after an update or reboot';
Check for new updates on Windows Update:
1: Open the Windows 10 "Start" menu and select the "Settings" item.
2: then select the "Update and Security" option.
3: in the "Windows Update" section, click "Check for updates".
4: If there are no updates, the message "You are up to date" will be displayed.
5: if there is any pending system update, the message "Features update for Windows 10 ..." will be displayed, then click on the "Download and install" item to start the system update.
6: wait for the update download to finish and restart the PC, or schedule a restart to be able to finish the procedure.
Run system file checker and disk error checking;
Open CMD (Command Prompt) as administrator;
Copy and paste the commands below followed by Enter after typing each command line;
Sfc /ScanNow
DISM /Online /Cleanup-Image /ScanHealth
Dism /Online /Cleanup-image /RestoreHealth
chkdsk /f /r
Wait for the process to finish and restart the pc;
Check if the problem still occurs;
I hope I helped, even more!
