zsh: abort

Additionally a section of the window flickers red/black before it crashes. Resizing the window by any amount stops that.

To Reproduce Steps to reproduce the behavior:

1. Start the binary and wait for it to crash after downloading assets.

Expected behavior It should not crash. (and also not flicker)

Screenshots The window does appear but then disappears after the crash. The area in the window that is black flickers between black and red every frame.

Some time before the crash but after resizing to make the flickering go away:

Desktop (please complete the following information):

• OS: macOS 12.2.1 (Monterey)
• Platform: x64 (CPU: Intel i7 6700K)
• GPU: AMD Radeon RX 6900 XT
• Build number: 1.0.0-8919d98

If possible, I would also like to know where Alex stores the downloaded assets and other data.

Small update, i have a machine i can test this on now. So i will be looking into the issue as soon as i’ve got time to do so!

When would there be a fix to this?
