anyone knows any fix for this? @gKamelo @heroims @friend-lga

[devstas]

Until I figured it out. So far, I only see that this happens only on iOS 17 and when the application goes into the background.

Yeah. Any workaround you found?

What's happening is when user puts app in recent list to force close the app and as soon as user force closes the app the device is rebooted.

Not yet :(

[JGideon]

you can remove __weak UIWindow *weakWindow = window; to try to fix this problem.

Can you create a fork with this fix and include other fix as well. I mean this pull request (#84)

[rahulvyas]

@JGideon Have you created a new fork?

[rahulvyas]

__weak UIWindow *weakWindow = window;

What should I put after removing this?

Just use window instead of weakWindow.
