Site pages mess after backup from host

Hello,

I have WP6.5.2. and using child theme and the latest Woocommerce. After doing backup from host provider admin panel, my site pages getting mess abnormal with narrow pages and missing images when browsing from home page. But the admin site looks normal and functioning. While admin site is login, browsing the site page all look normal and good. That’s strange to me.

Can someone advise and help to fix this issue? Thanks in advance!
