Site is blocked by white screen in IOS

**Describe the bug**
When I visit [my company's website](https://n-hub.io/) in IOS metamask mobile app, the site is shown when it is fully loaded, but it is blocked by white screen after a few seconds.
The site is released in March, 2022 and it had been worked very well in both AOS and IOS.
However, when I revisit this site today, I can't use this site because of blocking white screen.
I can't see and interact with nothing. I can't even scroll or enlarge the screen.
To make matters worse, the site works well in specific iOS devices.
Can anyone give me a help?

p.s.
I am using nuxt.js@2.15.8

**To Reproduce**
Open [my company's website](https://n-hub.io/) with IOS metmask mobile app.

**Expected behavior**
The user can use the site normally.

**Smartphone (please complete the following information):**
- iPhone 11 pro, ios 16.1.1

Start by reproducing the report by opening https://n-hub.io/ in the iOS MetaMask mobile app on the stated iPhone and iOS version. Compare the behavior with the devices where the site works, using the reported Nuxt.js 2.15.8 context. The issue does not identify a repository file, test, or concrete change, so done would require isolating a reproducible cause and defining the affected behavior.
