The new "Enable magnifier" checkbox does not behave correctly upon NVDA Magnifier startup failure, e.g. when Windows Magnifier is already running.

There are various other issues with this checkbox and NVDA Magnifier failing to start. Please double check all these use cases.

Steps to reproduce

• Start Windows Magnifier
• Try to start NVDA Magnifier; as expected, it should not start
• Open NVDA Magnifier settings
• Try to toggle "Enable Magnifier" checkbox

Actual behavior

The checkbox "Enabe magnifier" is checked and cannot be unchecked

Expected behavior

The checkbox "Enable Magnifier" should not be checked since NVDA Magnifier is not running.
