Using Arduino IDE 1.8.11 (Windows Store 1.8.28.0) on Windows 10 64 bit (VirtualBox)

1. Start the Windows Store version of the Arduino IDE.
2. Sketch > Include Library > Add .ZIP Library... - the dialog does not open and the IDE freezes and must be killed using Task Manager.

The problem only occurs when I launch the IDE from Microsoft Store, or the app pinned to the task bar. It does not occur if I start arduino.exe or arduino_debug.exe directly from C:\Program Files\WindowsApps\ArduinoLLC.ArduinoIDE_1.8.28.0_x86__mdqgnx93n4wtt.

The problem does not occur with the standard Arduino IDE 1.8.11 or 1.8.11 Hourly Build 2020/01/31 09:33 (tested on Windows 10, Linux 64 bit, Linux ARM 32 bit).
