Whatapp business doesn’t open or load on my iPhone, it closes back when I open it

Hello, please help me. My Whatapp business doesn’t open or load on my iPhone, it closes back when I open it. I have normal WhatsApp on my iPhone but I need WhatsApp busienss for my business contact, it was working before but it just stopped loading, it doesn’t even get the welcome page, it closes after it opens, I included a screenshot, it just stays on that page and closes back. I have deleted and installed again up to 10 times but still the same, what should I do Apple family?
