Are you using the latest release version? Yes
Can you reproduce it? Yes
Does it happen for a new document? If not do you have a document you can share that shows the problem? Doesn't happen for a new file.
What is your operating system and version (Windows 10, OSX Mojave, iOS 12 etc)? Windows 10
What happened for you (and what you expected to happen) Everytime I try to open the previous file I was working on, Designer crashes. It will open a new document and other documents I have worked with fine.
Provide a recipe for creating the problem (step-by-step what you did).
Screenshots (very handy) or a screen capture/video.
Any unusual hardware (like tablets or external monitors or drives that may affect things) or relevant other applications like font managers or display managers.
Did this same thing used to work and if so have you changed anything recently? (software or hardware) This is the first time I have experienced this problem, I havn't changed anything on my computer and have been using Affinity for a few weeks.
