glitch with switching phone orientation

sometimes after viewing a YouTube video in landscape on my iPhone (iPhone 13 max pro) the iPhone will not switch back to portrait, this also happens in WhatsApp. to resolve the issue i will have to close the app and reopen it. When i swipe up the app (YouTube/WhatsApp) show up in landscape on the list of apps. I have had occasion where that problem landscape/portrait switch issue just happens. this issue is intermittent

is any one else experiencing this or has a fix.
