I want/need to make this code run inside OBS as a script. I took this OSC Sender for OBS that it does what the name says: it sends OSC messages. But, inside the code, the server part is commented, because it doesn't work... right out of the box. It is needed to run OBS with LD_PRELOAD=/path/libpython3.7.so.
I modified the code but (uncommented lines) but, when server is opened, OBS stays unusable, blocked. So, I tried the "Async Server" - "Concurrent Mode" of python-osc. I take the example from its wiki (that it works in a console) and I mixed with the other script. I made a nice code... but it makes something weird. This is the code:

I'm not a programmer, so asyncio is a mess for me. I don't understand it. But I know what it does and what I'd like it to do.
When the script is loaded (in script_update(settings)), it opens the server and run loop() function. This function is a 5 seconds loop that prints some text. If I connect to the correct port from PureData and send some OSC messages, these messages arrives to OBS... but all of them drops together when the loop finishes. Meanwhile, there's nothing, OBS is blocked and nothing is in Script Log.
If I run the python-osc asyncio example code in a console, while loop is being executed, every Loop 0, Loop 1, etc, and every message arrives and all of them are printed at the right time.
How should I get this code to work? I need to open that server and run a much more code at the same time. I'm using OBS like a game engine.
