Page disappeared

One of my pages disappeared when I tried to manage user permissions. Before disappearing completely, it changed levels several times for no reason and disappeared and appeared back several times.
Now on the builder side, when I select "Pages " tab, Knack freezes and does not allow me to load any of the existing pages or go back to other tabs.
I get “Wait” and “Exit” option after few minutes and on exit I get Error code : RESULT_CODE_HUNG

On the live app, only disappeared page throws error.
