there are some issue in fragment

Question

I created an app.

It was running well for 1 month, but today I see that it crashes.

When I created the app, I used targetSdkVersion=30, and minSdkVersion=16.

But now there are some issues.. I think it happened due to Version. Is it possible ?

I tried the following...

I upgraded all the libraries and all the versions but it is not running, and errors are being displayed anywhere in any activity.
