I downloaded the mod manager for linux but it doesn't launch at all. I tried running it from the terminal and there was no output.

On version 0.0.5, it doesn't work in my environment either.
No errors or other messages and it exits with status 255.

On 0.0.4, it fails with this message with SIGABRT

Unhandled exception. System.InvalidOperationException: Default font family name can't be null or empty.

I've solved this problem.

This problem occurs when the system language is set to non-Latin characters such as Japanese and Korean.
So it works when the locale environment variable is changed like this.

$ LC_ALL=C ./BeatSaberModManager

That's an upstream issue unfortunately, see AvaloniaUI/Avalonia#4427

[SlipperyPete]

Just had the same issue, needed to install fonts mentioned in upstream issue to workaround, upstream issue looks like it has a integrated workaround now and is close to being actually solved though.

LC_CTYPE=en_US.UTF-8 are also works

This still happens to me even when trying both LC_ALL and LC_CTYPE, any other fixes?
