I have been using Opera GX as my main browser on my (M1) Mac (Monterey) for about two months, and it has worked just fine. Then at around 1:30 PM PST today, it closed and deleted my desktop shortcut. I went back into my downloads and reopened it, and all of my tabs/save information were restored... and then about a minute later it closed again. I have reopened it countless times since, and every time it closes and deletes the shortcut. I tried other Opera browsers like the main version and Opera Beta, and they have the same problem. Strangely, Opera Neon does not have this problem, and I was able to use it just fine.
