Version: Affinity Designer (Windows): 1.9.1.979
I got quite big problem with crashes during copy or duplicate - this is not strictly related to version above - it was also occuring in several previous versions.
I'm attaching example file, repro steps and crash dump.
Steps to reproduce:
1) open attached test.afdesign file
2) ctrl+a
3) ctrl+c
I got similiar crashes previously on various projects. Somewhere on the forum I've read that disabling windows clipboard history might help - and it helped for a while, but now happens again.
