After some antivirus activities, my partner development machine face
issue above.

This may due to some permission setting in Temp folder. To solve it,

1. Go to %Systemroot%, normally C:\WINDOWS or C:\WINNT
2. Right-click the Temporary folder (mine is C:\WINDOWS\Temp) and
select Sharing and Security. Select the Security tab and take a look
at the list of "Group or user names:"
3. NETWORK SERVICE should be in the list. If it is not, click Add and
type Network Service in the text box:

4. Make sure NETWORK SERVICE have Full Control in the Permissions list.

5. Click OK.

6. Restart IIS (Run iisreset)

Test on the web, and it solved.
