Port selection dialog under "Tools" is greyed out/unselectable

[AzyFloof]

Describe the problem

After upgrading to 2.3.3 the Port option under Tools is greyed out. The IDE won't let me select any boards, regardless of which ones I have plugged in.
Uploading sketches obviously fails because of this, because the IDE thinks I don't have a board connected.
Using the Board/Port selection dropdown shows no boards listed

To reproduce

Plug in any arduino (I tried a bare ATMEGA328 with an FTDI dongle, an Arduino Micro, an Arduino Leonardo, and a Pololo A*Star 328 16MHz).
The ports option under tools is greyed out and I cannot select any board

Expected behavior

I expect a list of plugged in and supported boards to appear as a list under the Ports sub menu, and under the boards/ports dropdown list

Arduino IDE version

2.3.3

Operating system

Windows

Operating system version

10

Additional context

The issue is not present in 2.3.2 if I downgrade
I've tried uninstalling and reinstalling 2.3.3 manually but the issue persists
The ports of the connected boards show up in the device manager list in Windows
The problem persists if I try different cables and different USB ports
All my drivers are up to date

Issue checklist

• I searched for previous reports in the issue tracker
• I verified the problem still occurs when using the latest nightly build
• My report contains all necessary details

Please do this:

1. Close all Arduino IDE windows if the IDE is already running.
2. Start Windows "File Explorer".
3. Open the Arduino IDE installation folder
   (usually C:\Program Files\Arduino IDE or C:\Users\<username>\AppData\Local\Programs\Arduino IDE).
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.
   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 up completely.
9. Switch back to the PowerShell window if the Arduino IDE window took the focus.
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. Paste (Ctrl+V) the output in a reply to this GitHub issue thread.
