OBS Crashes if Controller is connected before startup

[D34dlyK1ss]

Describe the bug
If I have my controller connected (USB) to the computer before opening OBS, when I try to open it, it crashes. This doesn't happen if I connect the controller after OBS starts

To Reproduce
Connect a controller
Start OBS

Getting the same issue issue, on Ubuntu 24.04, OBS 31.0.0, input-overlay v5.0.6

The plugin seems to load correctly:

info: [input-overlay] Loading v5.0.6-HEAD (c99a526) build time 2024.10.24 17:24
warning: DEPRECATION: obs_frontend_get_global_config is deprecated. Read from global or user configuration explicitly instead.
info: [input-overlay] Initializing SDL2 for gamepad input (compile-time: 2.0.20, run-time:  2.30.0)

But then I get a segfault once all the plugins are loaded:

Only happens when my controller is already connected to my computer when obs starts

Can you run gdb obs -ex run then once it crashes run bt and paste the back trace here? I want to check if it's the same function that's crashing.

Well it seems like I can't reproduce that crash anymore... My setup hasn't changed so I don't know what the issue was

[loicmagne]

Oh nvm, I managed the reproduce the crash, so for some reason it only happens when my gamepad is connected via bluetooth (and not usb). Here's the output of gdb obs -ex run/bt
