Windows 10 x64
Affinity Designer crashes when I copy (CTRL + C) one shape and then paste the fills and strokes using CTRL + Shift + V. This happens only every once in a while, but I've managed to reliably recreate it in the attached project file.
Both layers exist within a symbol, which has two instances in the project. If I first detach both symbols, the crash does not occur.
See attached project file.
