GrapheneOS
I am so sorry for making noise. And I feel a bit ashamed remembering that it was my own doing.
Now I realize the reason for the recommendation from advanced users here that one should never mess around with system apps. Lesson learnt.
I/We have had but smooth and nice experience with GrapheneOS and updates, even Alphas, for which we are grateful to all of you working so hard on this project. Unfortunately, I don't find an edit button to edit my previous post to add that this was caused by me and not by the update to the system.
