Whole layout gone

Hi there,
Since today (I think) the whole layout of my homepage is suddenly gone.
What I’ve tried, but hasn’t worked:
– deactivated plugins one by one
– tried in a different browser

I did do some updates this morning, but can’t remember which one exactly and don’t know how to figure out which I did.

Not all my pages have this problem, only the homepage (which I edited with Elementor- could that cause a problem? Removing Elementor plugin didn’t help..)

I’m guessing it has to do with my theme Zakra, but am not sure.. Can anyone please help me? Thanks so much!
Kind regards,
Roos
