Pressing F13 crashes Deadlock + Steam only while in a party on Linux

[soaf]

If I am in a party and press F13 the game and Steam crash. This only happens when I am in a party. I only experience this bug on Linux. I tested this on a Windows device and the bug does not happen.

I use a foot pedal for push to talk in discord, this is what is sending the F13 key press.
