When I try to add the MidiIn/MidiOut node, the project auto-closes and broken, making it impossible to open again.

My system: Godot 4.2.2stable

It's somewhat known issue but I've not expected that to crash Godot. I wrote that this issue is known in readme. Can you try to instantiate midiin from script? If it's also crash Godot I'll look into it.

I noticed that godot broken even without try to add MiniIn/MidiOut node. It broke when i add godot-rtmidi in addons folder and try reopen project for the second time.

But i try to instantiate MiniIn/MidiOut from script before reopen project and appear this error:

I don't have access to Linux PC but tried using WSL. I can confirm godot-rtmidi crashes godot. Here is what I get:

I'm going to compile godot-rtmidi from source in WSL instead of using CI artefact. Let's see if it solve the problem

I've re-uploaded the latest release with a recompiled Linux binary. Can you try it out? Even if it works, we still need to catch exceptions thrown by RtMidi to ensure it doesn't crash Godot. However, I'd like to know if it functions correctly now.

[italomcs]

Godot doesn't crash but this error appears and rtmidi doesn't work.

godot-rtmidi_alsa.zip

Can you try out this one? I've compiled for alsa only.

Edit: Also sorry for temporary solutions. I don't have time these days to develop proper solution.

[italomcs]

I tested godot-rtmidi_alsa and it works! (It sent and received messages normally).

But this errors appear when i add script with MidiIn/MidiOut class.

-modules/gdscript/gdscript_compiler.cpp:121 - GDScript bug: Native class "MidiIn" not found.
