Tank 2 update issue

Dear team,

After upgrading to Android 14, it was working great. after that, there were a system update, after downloading it there were unzipping issue. Didn’t install it. after a week, there were a new update, I unfortunately installed it and it had created a lot of issues, links in WhatsApp is not opening, PDF  documents is not opening. A lot of  applications are not working any more “Stopped working” error message.

Is there a solution for this issue? How can I roll back?

Your support will be more than appreciated.
