What should be the solution to it?
Any help will be appreciated.
I tried to debug it for many times but no success, please help me with this.

EDIT

"UICollectionView (<UICollectionView 0x7fd6ca190000>) is stuck in its update/layout loop. This can happen for many reasons, including self-sizing views whose preferred attributes are not returning a consistent size. To debug this issue, check the Console app for logs in the "UICollectionViewRecursion" category."

Error description for crash

Solution 1:^[1]

We were experiencing the same error with our iOS app using Xamarin.Forms. We were able to resolve the issue by explicitly specifying the height of the items in the collection view. Not a permanent solution, but should be able to get you past the crash.

Solution 2:^[2]

I am here https://github.com/WenchaoD/FSCalendar/issues/1351 Answered similar questions on the; The preliminary judgment is that the total width of the item exceeds the screen width when calculating the item size in layout. It is suggested to use floor to round down when calculating the item size to temporarily solve this problem; The same code is in ios15 Version 2 can run normally before; In addition, it is very strange that I have no problem on iPhone 11, and the flash back will appear on iPhone 11 Pro max

Solution 3:^[3]

https://github.com/xamarin/Xamarin.Forms/issues/15230 mentiones a couple of workarounds. I know it is Xamarin.Forms, but under the hood the ItemSizingStrategy="MeasureFirstItem" probably translates to an iOS property on the UICollectionView

Solution 4:^[4]

I have faced this issue, it was solved.

In my case, the root cause is the overwrite methods inside the subclass of UICollectionViewFlowLayout have a bad implementation, they keep all collection sizes (cache them) to re-use later which instead of should be calculated whenever the delegate invoke to.

So, you should review the classes inherited from UICollectionViewFlowLayout to make sure they have no reference cycle and should have no recursion, and keep it safe.

Hope you have a good solution.

Solution 5:^[5]

I had similar issue in iOS 15. In my case it was fixed by overriding UICollectionViewFlowLayout method:

override func shouldInvalidateLayout(forPreferredLayoutAttributes preferredAttributes: UICollectionViewLayoutAttributes, 
         withOriginalAttributes originalAttributes: UICollectionViewLayoutAttributes) -> Bool {
    return true
}
