I can't reproduce - could you share your project?

Thx for your reply!

Pls find a simplified version of my project attached. I replicated the issue in QGIS 3.2.1.
(The background is geospatial research on transport and social exclusion. Feel welcome to have a look at our webpage)

Regarding the nitty-gritty details of the crash:
Apparently, it was not the deletion of one section in the layout manager that made QGIS freeze. The problem seemed to appear when clicking "edit" to enter the next section (after having selected it by clicking).

(Furthermore, the problem might have to do with the speed of doing these things. When I waited 10 seconds between selecting a section and hitting "edit", I could delete and edit it as well as several other sections w/o any further ado. Maybe the underlying scripts just hadn't kept up to my pace at the first attempt.)
Edit: This assumption is probably wrong. I just tried again. When waiting 30 seconds in-between, QGIS froze again.
My workaround: Delete a section, save report, close layout, open layout again, delete next section, save report, close layout, repeat. In one attempt, I got a crash report, see below.

Hope that helps.
Cheers

NB: I'm out of office and won't be able to reply until mid-September.
