iPhone X IOS 11.2.6 crashes and WhatsApp Issues

[Nadav_A]

Hey All

I have an iPhone X IOS 11.2.6 and it’s been the 5 times I’ve had to restore my device because of something that related to WhatsApp.
The problem appears after few days.
The symptoms are:
1. Cannot open the Photos App.
It happens after I save a photo I got on WhatsApp.
2. One at the time apps crashes.
3. Cannot open WhatsApp.
4. Search isn’t possible (also crashes)

And some other strange issues.
I also have a video that shows the problem.

Please help me to solve this situation.
Thanks,
Nadav
