I can´t see and install any libraris in my Library Manager

I'm going to ask you to provide some additional information that might help us to identify the problem.

This procedure is not intended to solve the problem. The purpose is to gather more information.

Please do this:

1. Select File > Quit from the Arduino IDE menus if it is running.
   All Arduino IDE windows will close.
2. Start Windows "File Explorer".
3. Open the Arduino IDE installation folder.
   ⓘ The default installation location is at one of the following paths:

   • C:\Program Files\Arduino IDE
     

   • C:\Users\<username>\AppData\Local\Programs\Arduino IDE
     

     (where <username> is your Windows username)
     If looking for it with your file manager or command line, note that the AppData folder is hidden by default. On Windows "File Explorer", you can make it visible by opening the "View" menu, then checking the box next to "☐ Hidden items".
4. In the folder listing of the Arduino IDE installation folder, hold the Shift key while clicking the right hand button on the mouse.
   A context menu will open.
5. Select "Open PowerShell window here" from the menu.
   Windows PowerShell will now open with the current directory set to the Arduino IDE installation folder.
6. Type the following command:

   & ".\Arduino IDE"
   

7. Press the Enter key.
   Debug output should now be printed to the PowerShell window as Arduino IDE starts.
8. Wait for Arduino IDE to finish starting.
9. Switch back to the PowerShell window.
10. Press the Ctrl+Shift+A keyboard shortcut.
    This will select all the text in the PowerShell window.
11. Press the Ctrl+C keyboard shortcut.
    This will copy the contents of the PowerShell window to the clipboard.
12. Open a forum reply here by clicking the "Reply" button.
13. Click the <CODE/> icon on the post composer toolbar.
    This will add the forum's code block markup (```) to your reply to make sure the error messages are correctly formatted.
    
14. Press the Ctrl+V keyboard shortcut.
    This will paste the output into the code block.
15. Move the cursor outside of the code block markup before you add any additional text to your reply.
16. Click the "Reply" button to post the output.

Please let me know if you have any questions or problems while following those instructions.

i had to attach it as a file because there is char limit and i it is too long
here it is:

output.txt (136.8 KB)

Thanks. I see that Arduino IDE was able to load the index file that contains the list of libraries for Library Manager:

@kredenc

time="2024-09-21T22:32:52+02:00" level=info msg="Loading libraries index file" index="c:\\Users\\vitvr\\AppData\\Local\\Arduino15\\library_index.json"

I also see that it was able to install a library using the Library Manager infrastructure (this library is automatically installed by Arduino IDE on the first run after a fresh installation):

@kredenc

If you check Library Manager again now, do you see a list of libraries? I'm wondering if maybe the problem has somehow resolved itself since the time you encountered it. I don't see anything that looks relevant in the logs.

[kredenc]

Yes, it works now, I don't know how it's possible, but thank you

[ptillisch]

Yay! I'm glad it is working now.

@kredenc

I don't know how it's possible

I notice that the logs you shared show the IDE was installing some additional components, which it does after a fresh installation (the IDE is designed to download those components from the Internet to ensure you will get the latest version of them). Even though the IDE starts up and can be used while that is happening, the IDE won't be fully functional until those installations are finished.

My hypothesis is that when you tried to use Library Manager before, the installations were in progress, and this is why Library Manager wasn't populated. So the solution was to give Arduino IDE enough time to finish the installations. The installations should typically only take a couple of minutes so most people probably aren't affected, but maybe the installation took longer for some reason (e.g., slow Internet connection, antivirus blocking the process while it performs an analysis) on your system.
