Rust panic

[AfroMonkey]

When running cargo run I have a panic error.

I'm not familiar with rust, If I can attach more info, I'll be happy to do it

As shown in the error message (the lines with WARN client_backend), the TF2 launch options required for MAC to work are not detected in your Steam. Make sure you've added them (-condebug -conclearlog -usercon -g15) to your Steam launch options for TF2 and try running the program again. If you have the launch options and you still get the error, please follow up here.

For the maintainers: I believe it should be considered whether in situations like this, the client can be cleanly exited with a message rather than calling a panic!, such as by propagating error types back to the main function.

[AfroMonkey]

I don't think the warning is related, the game wasn't even launched. However, I add the launch options and still have the issue

[Conni243]

add --ignore_launch_opts after cargo run like this: cargo run --ignore_launch_opts

Other people had the same issue and fixed it using this

[AfroMonkey]

It works, thanks

cargo run -- --ignore_launch_opts
