IDE 2.1, No board manager, No Port, Fail in downloading libraries

Development Tools IDE 2.x
1

I have installed Arduino ide 2.1 and I'm running on windows 11 PC.

in my PC, IDE 1.8.19 also installed and run without any error.

But when open the IDE 2.1, It's only giving a blank sketch and when i searched for boards using board manager (ex: uno) gives "NO BOARDS FOUND FOR "UNO". " with "NO PORTS DISCOVERED".
even does not show any board or library in side menu too.

Although i have a proper internet connection and without using any proxy , in notification shows some kind of a error that "Some indexes could not be updated. Get "https://downloads.arduino.cc/packages/package_index.tar.bz2": proxyconnect tcp: dial tcp 192.168.43.1:44355: connectex: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.: https://downloads.arduino.cc/packages/package_index.tar.bz2

Even i can't open sample sketch or .ino file which created from another PC in IDE 2.1 (in IDE 1.8.19 those files are working fine)

finally the close button in the IDE window / quite option (Ctrl+Q) and close window from the task bar are not working (Not close the window), i have to go to task manger and have to click End Task to terminate the IDE 2.1 window.

Please help me with this problem

There is some bug or your file is corrupted try uninstall and reinstall it do not try it to repair

Tried in several time, Uninstall an reinstalled using different locations, using msi installer and zip also, but nothing changed.

i got something in network, i have previously used VPN and currently I'm not using any of it. but after a new installation of IDE is also show the same previous Proxy data in network menu (File>Preferences>Network)
seems like a cached data issue to me (but I'm not sure about that)

When I get in such a situation one thing I try is after uninstalling the offending app I:

Scour and remove

  • the Reg for remaining remnants of the previous installation.
  • Remnants in the program files folder
  • Remnants in the user app / local and roaming.

R u completely removing all files or not

Also do not use VPN if possible.and download from arduino website only

If problem continously after last try open a new thread with arduino ide catergory and alert the devloper for the same

With that you can use older version if having continous issue with 2.0
