The new version of Ableton Live 12.3 has a big issue in the M4L API.
I am sending OSC messages from GP widgets to control the level of Ableton Live Tracks using my own M4L device.
When the buffer size is set to 2048 samples in Ableton Live there is a huge delay in the M4L API.
I reported to Ableton and after some test case they have been able to reproduce.
Now there is a new public beta version available and the issue is fixed.
