After Publish Sorry! That page doesn't seem to exist

After publishing any page on 2 of my sites and launching the builder I am receiving the error
Sorry! That page doesn’t seem to exist.
After unpublishing the page appear normally again and can be edited (with same link).
Standard pages like Home, Online store, Cart work normally even after publishing.
Only new pages give the error after publishing.
I tried refreshing permalinks and flushing cache without any effect.

Will appreciate anyone help
