[macos] Application is blank

[achou11]

Installed v16 using homebrew and when I open the application, it seems to just be a blank window that doesn't do anything upon input.

Not sure if relevant, but when running via the CLI (using /Applications/Gauntlet.app/Contents/MacOS/Gauntlet), I get the following error:

Seems like plugin runtime cannot start. I do not have intel mac to test, so I am going to ask you to provide logs:

open -n /Applications/Gauntlet.app --stdout ~/gauntlet.log --stderr ~/gauntlet.log

Also you could try to see if there are any errors related to Gauntlet in Console.app

Seems to be the same output as what I initially reported:

Nothing notable showed up for me :/

Installed the v18 release and ran open -n /Applications/Gauntlet.app --stdout ~/gauntlet.log --stderr ~/gauntlet.log again.

Got an almost identical output aside from the last 2 lines (mentioning tokio-runtime-worker):
