Can confirm this one, since I have tasks scheduled to run and switch system themes at certain times of the day (i.e. when it's night or first thing in the morning) and the app crashes whenever the theme switching happens.

Describe the bug: (Found a similar issue #522 , maybe you can close this one after you solve it :) ) I use Auto Dark Mode for auto-switching my theme. Every time the theme change happens, the app just crashes. Soon after the switch, I can invoke the flyout while I can't open the setting panel. A hour (maybe sooner) after the switch, the app will be totally down. To Reproduce: Steps to reproduce the behavior: Install and launch Auto Dark Mode Wait or invoke a theme change (taskbar color and app theme included) The setting panel starts to crash The whole app is down. Screenshots: (It will crash, so no screenshots 😥) OS Version: Windows 10 Version: 21H1 (19043.906) ModernFlyouts Version: Version: 0.9.0.1 (Latest for now)

For anyone looking for a workaround, I wrote a script to automatically restart ModernFlyouts when a crash happens. Let me know if there's anything that needs changed.

_{modernflyouts.vbs:}

Set WshShell = CreateObject("Wscript.Shell")
WshShell.Run("powershell -windowstyle hidden -executionpolicy bypass -noninteractive & { $app = (get-appxpackage -name 32669SamG.ModernFlyouts | select -expandproperty PackageFamilyName) ; start shell:appsfolder\$app!App } "),0
Set WshShell = Nothing

You will need to provide the path to the script as a program argument in the task.
