Hello
I would advise you to send the watch in and have it repaired under warranty. The problem your watch has clearly looks like a warranty case to me. In my opinion, this is not normal. My watch has never done this before.
I hope I have been of some help.
Many greetings.
This watch shows "Casio" if you hold down the lower right button for more than 3 seconds. So probably this button blocks itself in your watch.
