Permissions of the \tmp path are missing. You can try to run
plesk repair fs <your domain> -y
but probably it is not a Plesk issue, but rather an operating system issue. If the above Plesk repair command does not help, you'll need to set permissions on the operating system level. At you rown risk you could try
icacls "G:\PleskVhosts\<your domain>\tmp" /grant:r BUILTIN\IIS_IUSRS:(OI)(CI)(M,DC)
Maybe it helps.
