[Affinity crashes everytime I copy an artboard from one file and paste it into another file]

I have two opened files and what I'm trying to do is copy one artboard from one file and paste into the other file. 

I can copy it without any problem, but as soon as I press cmd + v on the other file (where I want the artboard to be pasted), the program crashes instantly, I did it more than 5 times and it just keep happening.

I'm on macOS Catalina v 10.15.7 and using Affinity 1.8.4

[Affinity Designer for MacOS - 1.7.0]

This is greaaat! I'm trying to update my Affinity Designer to the new version but for some reason I don't find how/where. In the website I can only see the option to buy it

[Vector cutting tool (knife/scissors)]

Hi everyone! I'm struggling because I need to cut some vectors but I'm unable to do it without the knife or scissor tool :( And I don't understand exactly why, but when I break the curves I want to delete, everything goes black and it's a mess.

Does anyone knows when are we going to have some vector cutting tool available? 

 

Thanks! :)
