The cause of the problem is that your system time is incorrect. You can fix it by syncing the system time. I'll provide instructions you can follow to do that:

1. Right click the Windows Start icon (⊞) on the taskbar.
   A context menu will open.
2. Select "Settings" from the context menu.
   Windows "Settings" will open.
3. Select "Time & language" from the navigation panel on the left side of the window.
4. Select "Date & time" from the list at the right side of the Settings window.
   The "Date & time" settings section will expand.
5. Click the "Sync now" button that is located under the "Additional settings" section of the window.
6. Wait for the syncing process to finish.
7. Close any Arduino IDE windows that are open.
8. Start Arduino IDE again, as usual.
   ⓘ It is not required to start the IDE from the PowerShell terminal this time.

This time Arduino IDE should start up fully and work as expected.
