Reproduction: I open Affinity Photo 2.4.1, create new document 1000x1000px, do a File>Place (linked by default) and select the EPS files I want (there are 10), I click in the midpoint of the document to place them, and after I've placed 2 to 8 of them the program crashes. I retested this sequence 4 times. Attached are the EPS files I selected.
The crash doesn't happen if I select/place one at a time (document dimensions, choice of EPS files, placement-mode all remain unchanged).
