I’m sorry to hear about your application crashing issue. It must be frustrating.
Crashes can occur due to various reasons like software conflicts, system issues, or even specific file problems. This situation requires a thorough investigation and escalation.
I recommend submitting the crash report that you receive when reopening the app. It contains valuable diagnostic information that can help pinpoint the issue. Also , please share the email address you’re using on the crash report form.
To protect your privacy, I’d advise against sharing such sensitive information on the forum. Instead, please send a quick email to productsupport@sketch.com, and we will take it from there ASAP.
UPDATE: Additionally, our engineering team asks if you have a second non-retina display attached to your setup. While this is uncommon, it has been known to cause similar issues in the past. If you do have a second non-retina display, could you temporarily disconnect it and use Sketch without it for a while?
