Front Page is coming as a different page altoghter sometimes.

Hello,

I’m facing a bit of a problem here and I’ve tried every possible solution. I have designated a specific page as the home page, but for some unknown reason, a different page keeps appearing out of nowhere. I have attached a screenshot of this unexpected page. It seems to be a blank white screen, but previously it was displaying a subscription page.

Additionally, I am attaching the actual home page as it is supposed to appear.
