Hi @Anahitarad,
Welcome to the community.
Can you please test it in safe mode and see if it does the same thing?
This would indicate that the issue is being caused by a third party app. At this point there are a couple of options.
You can uninstall apps one by one and test after each to see if you can identify the one that was causing this. Alternatively you could run a software repair using Xperia Companion on your device, but this will erase everything so make sure you back up.
