Does this happen in live, preview, or when you deploy it? Can you share the item with us so we can see what is going on to see if we can replicate it?
cannot share sorry, however we seem to have issues affecting some users when opening the experience from a bookmark in the preferred browser (edge or Chrome).
9/10 times it loads fine. some times slower than liked but it loads. Then on random occasions it continues to load and the url refreshes only ever showing a white screen.
when the url is opened in another browser its fine. on all browsers. Then out of no where it occurs again.
one user struggles to open on any browsers. Cache has all be cleared and site hard reloaded and nothing.
