This could be one of the reasons. But the problem also happens for files with no linked resources. I rarely link resources for my files because my resources are located in a cloud drive which could cause problems when I share the designer file to my coworkers.

Using 2.3.0 on my M1 MacBook Pro 14" running macOS 14.1.2 (23B92). In the past couple of weeks it started to fail opening files that's larger than 200MB in file size. Sometimes it took 10min or so to open the file eventually, but most of the time it just says opening file in the title bar without anything actually happening for even hours. Trying to quit the APP shows a popup saying there's a file being opened so the APP won't quit. Force quitting the APP works but the problem persists when opening files larger than 200MB again. I solved this by removing Affinity Designer 2's permissions to open any file or folder in macOS System Preference > Privacy and Security > Files and Folders (disabling all sliders in this setting). I can then open any .afdesign file without any problem. Whenever I enable the sliders, the problem reappears. I can now use the APP without any problem with those permission sliders disabled. But I think this is a weird bug so I would like to share with you guys. Just so you know.

Thank you! Tried it and it works. Gotta keep it in English for now...

Thank you for the follow-up. That would suffice for the moment. Awaiting the update.

Found this topic at last...I have the same problem as well. My touchpad on MBP 2016 13" with Touch Bar works fine with all apps, but some months ago the Pinch to Zoom stopped working from time to time. I could fix it by turning the pinching functionality on and off several times in system preference. By it kept happening and it bother me, especially when Im working on a design and zooming in and out is a very often task. I tried to pin-point the source of this issue and found that Affinity Designer is the reason. My other apps (Adobe PS, AI and other stuff) work just fine. But whenever I launch Affinity Designer, there's a 90% chance that after some time the Pinch to Zoom will stop working. By quitting Affinity Designer, the pinching would work again after some more minutes. I tried to turn off every touchpad related option in AD but the problem is still there. It's not a big issue, but somewhat inconvenient. Turning the pinching on and off in system preference is by far my only solution whenever this problem occurs, since it always happen when I have loads of design to work on AD and restarting can be a pain in the ... BTW, I have another MBP which is a 2015 model that comes with a conventional trackpad (instead of a force-touch version), and this problem never occurs. Could anyone in Affinity dress the issue?
