Android Question try-catch does not work

Hello friends,

I am working on a B4A project and I got java.lang.NoClassDefFoundError: Failed resolution of: Ljava/util/Base64 error on Android 7.

I tried using try-catch to handle this error, but to no avail. The application closes completely on some devices (force close)

I jetified the library but it didn't work.
Why doesn't try-catch work in this case?
Is there a solution to prevent the app from force closing?
