E484: Can't open file c:\Users\username~\AppData\Local\Temp\VIo7EE2.tmp

On Windows 10, i am facing this issue. Unable to open the temp dir for writing.

My _vimrc file:

`let $TMPDIR = "C:/Users/Balasubramanian/.vim/temp"

" initial vundle configuration.
set rtp+=~/.vim/bundle/Vundle.vim
call vundle#begin()
"plugin installation
"vundle plugin

Glaive codefmt google_java_executable="java -jar C:/Users/Balasubramanian/.vim/bundle/vim-glaive/google-java-format-VERSION-all-deps.jar"
`

Can the community please help me ? every time i have to format the code, i am using a Visual Code to format it and i have to switch back to Vim for coding.

I have also disabled my "RealTime Scanner" , even then, get the same issue.

Thanks

Start with the reported _vimrc configuration, especially the $TMPDIR setting and the google-java-format Glaive command, then reproduce formatting on Windows 10 to observe E484 for the temporary file. Confirm the issue is resolved when formatting can create and write its temporary file without requiring Visual Studio Code.
