Addon updates fail to download solved

[AbitFishy]

I was trying to update my addons, but all the downloads failed with the error "download failed". In the log, I found this line

System.Net.WebException: An exception occurred during a WebClient request. ---> System.UnauthorizedAccessException: Access to the path '\snip\\AppData\Local\Temp\Playnite\playnite-successstory-plugin.pext' is denied.

Navigating to the folder Playnite I did get an access denied error and required Admin to open it. The folder was empty. I deleted AppData\Local\Temp\Playnite folder and I could update my plugins again.

I don't know what screwed up the permissions, but I figured other people might run into this problem, so it might be worth adding it to the wiki.
