MobiFlightWwFcu.dll crash when waking PC up from sleep

[leftos]

Describe the bug If I put my Windows 11 PC to sleep while MF Connector is running with a WinWing FCU profile active, and then wake it back up, it crashes. This is 100% reproducible.

Steps To Reproduce

1. Start MF Connector
2. Load up a WinWing FCU profile (a few of these at flightsim.to) and pair it to the orphaned WinWing FCU device if necessary
3. Put PC to sleep
4. Wake PC up
5. Notice crash report from Windows on MFConnector.exe

Expected behavior Shouldn't crash.

Actual behavior It does crash.

Details

• MobiFlight Version: Confirmed on 10.3.0 relase, and GitHub repo head

@Koseng can you take a look at this?

Hi, yep I can check where to best catch that case.

Crash will be fixed, but either way MobiFlight will need to be restarted, because Joystick reconnect is still not implemented.
