Your system information

Please describe your issue in as much detail as possible:

Dota 2, using "-vulkan" launch option, randomly crashes during local server bot matches (games with human players not tested) in all several recent updates. After completely reinstalling Dota 2, games can be played from start to end without any glitches; however, if there is a new version of Dota 2 and it requires itself to be updated to be played, after updating it, the client randomly crashes during almost all match hosted locally.

Steps for reproducing this issue:

  1. Install Dota 2 in Steam on macOS Mojave;
  2. Check for updates. If there are any, download the update;
  3. Start up the client in Steam with "-perfectworld -vulkan" boot parameters. The updated client crashes during bot matches hosted on local machine.
  4. Didn't know if any crash happen during match hosted remotely on official server, or without "-vulkan", or with "-opengl"

Firstly, sorry for the duplicate.

This is also occurring during online play. Crashes straight to the desktop, without warning. The odd game completes without any issues. I'm finding issues when using both Vulkan and Open GL on lowest settings.

Occuring when running external monitor and also when running natively on the MacBook. Seems to happen more often when playing versus heroes with illusions or detailed animations - but cannot confirm.

This is continuing to occur. I can confirm this is only happening when using Vulkan, when I switch to OpenGL the game doesn't crash.

👍 I can confirm this as well. I have not tried switching to OpenGL. Crashes happen without any error output as well when started using shell script on terminal.
