ArduinoIDE 2.2.1 keeps giving me a blank page after installation for windows 11 what's the problem??

Why did you post this in the section for IDE 1.x?

I will move your topic for you. Please read the sticky post at the top of each forum section to know if it the correct place for your question.

Hi @louil. I'm going to ask you to post 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:

Close all Arduino IDE windows if the IDE is already running.
Start Windows "File Explorer".
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".
In the folder listing of the Arduino IDE installation folder, hold the Shift key while clicking the right hand button on the mouse.
From the context menu, click "Open PowerShell window here".
Windows PowerShell will now open with the current directory set to the Arduino IDE installation folder.
Type the following command:
```
& ".\Arduino IDE"
```
Press the Enter key.
Debug output should now be printed to the PowerShell window as Arduino IDE starts.
Wait until you are sure the IDE startup has gone into the hang state
(as indicated by no additional output being printed to the terminal).
Switch back to the PowerShell window if the Arduino IDE window took the focus.
Press the Ctrl+Shift+A keyboard shortcut.
This will select all the text in the PowerShell window.
Press the Ctrl+C keyboard shortcut.
This will copy the contents of the PowerShell window to the clipboard.
Open a forum reply here by clicking the "Reply" button.
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.
Press the Ctrl+V keyboard shortcut.
This will paste the output into the code block.
Move the cursor outside of the code block markup before you add any additional text to your reply.
Click the "Reply" button to post the output.

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

On the first run after a fresh installation, Arduino IDE downloads some additional essential components from the Internet and installs them. If it can't install those components then the startup fails. So the computer must have access to the Internet on the first startup.

The errors indicate Arduino IDE is not able to access the Internet. If it is not already, please connect your computer to the Internet, close the Arduino IDE window, then start Arduino IDE again. This time it should start up successfully.

After that first run, an Internet connection is not required. However, there are some supplemental features such as "Library Manager" that have an inherent dependency on the Internet. Those features will not be usable while your computer is offline. But the essential functionality of editing, compiling, and uploading sketches will be available even without an Internet connection.
