Empty sidebar (RtL lang)

I am trying to make the sidebar not empty. I tried changing the “primary sidebar” (both in wp admin and elementor) and it keeps being empty. I tried also moving to English just to see if it fixes it, it didn’t.

(Not sure if related to this https://ww.wp.xz.cn/support/topic/recent-update-emptied-side-menu/)
