My sidebar disappears

I’ve submitted one page but the problem is with all posts. The sidebar which I’ve set to be sticky disappears and I can’t scroll to the bottom of the page, it jumps up as we do so. It appears as if the sidebar widgets have been shifted to the bottom below which we can’t navigate.
When I disabled the sticky sidebar option, I could see the widgets, but they were at the bottom of the page right above the footer.
I tried disabling a few features, but couldn’t get it.
Also saw a similar query, so tried toggling the mobile cache, which too didn’t resolve the issue. Please guide me.
