Is there is any other way to solve this error ?
My code looks like this :
val bitmap = applicationContext.contentResolver.loadThumbnail(uri,Size(5,5),null)
thumbnail_image_view.setImageBitmap(bitmap)
screenshot_image_view.setImageBitmap(bitmap)

The method loadThumbnail() was only added in API level 29 that Android 10.0 so it won't work in lower versions.
However, you can use image loader libraries like picasso or glide with the uri.

Have you tried passing the context of activity or fragment instead of application context ?

Chuck IncompatibleClassChangeError

I make a simple app, that uses http. For debug previously I used Chuck library. But now, when I try to open http-package from Chuck I get exception and I don't understand why.

In XML file you are using different recyclerview and java you are casting different recyclerview that's why the error is coming. Use the same type of recyclerview in both XML and java file.

add this library is the same just with new features https://jitpack.io/p/Leogiroux/sweet-alert-dialog

try to add this line to your proguard file:
-keep class cn.pedant.SweetAlert.** { *; }
Reference of this Error solution. This is from Git Error issue page of SweetAlaert.

Remove the dependency from build.graddle and add it as a module as shown here:
https://github.com/pedant/sweet-alert-dialog/issues/148

This Library is not maintained
To solve this issue
Modify the File OptAnimationLoader
Add another else condition / case
case "YOURPATH.Rotate3dAnimation":
anim = new Rotate3dAnimation(c, attrs);
break;
