  • Open the folder C:\Users{username}\AppData\Local\Arduino15. That is under a system folder AppData, which Windows Explorer might try to hide from you unless you set it to show hidden items in the settings.
  • Delete any files named package_index.json, package_index.json.sig, and package_index.json.sig.tmp.
  • Now try opening Boards Manager again. It will download fresh copies of the files and hopefully the problem will be solved.

With this solution the manager functions well
Thank you !
