Describe the bug When switching between certain app themes, the app crashes and it cannot be started anymore. Tapping on the app icon only opens the app settings, but the 'open' button is missing.

I could reproduce this behavior in both the calendar and gallery app when switching from the 'dark red' theme to the 'white' theme.

To Reproduce Steps to reproduce the behavior:

1. Go to settings -> customize colors
2. Select the 'dark red' theme
3. Go back to the app's main screen
4. Go to settings -> customize colors
5. Select the 'white' theme
6. Go back to the app's main screen
7. The app closes/crashes.
8. Try reopening the app.
9. The app's android settings are opened, but there is no 'open' button.

Expected behavior The app opens normally no matter which theme is selected.

Screenshots N/A

Device info (please complete the following information):

• Model: Google Pixel 6a
• OS: Android 14 (Graphene OS)
• App Version: gallery (1.1.0) and calendar (1.0.2)

Additional context I tried clearing both storage and cache, but that didn't resolve the issue. I had to completely reinstall the apps to make them work again.
