The problem relates to MIDI learn, The bound control is not available at session load. deleting line 4738 in the session file makes the session load again

Thanks, good to know. But is this still considered being a bug?
And we're you able to reproduce the exception when, after closing the error dialog, loading a recently used session?

Had a similar error on Ardour 7.3 ArchLinux and couldn't open the project. I had MIDI-learned a Faderport2 through QMidiRoute to drive some automation, then closed the project. Reopening without Faderport/QMidiRoute attached.

ERROR: Unexpected exception during session setup: tr1::bad_weak_ptr

I removed the lines
      <Controls>
        <MIDIControllable id="224482" event="0xb0" channel="0" additional="0x0"/>
      </Controls>
from the *.ardour session file and was able to start the project again. The weekend is saved :)

Can you describe in more detail what you're doing with MIDI learn that ends up with this problem?

I have tried to reproduce this on a fresh session with the below steps, but unfortunately without success so far, so I can only describe what lead to the error:

* I routed drum instrument tracks to a drum bus
* I put LSP parametric EQ on that bus with a high shelf activated
* I opened an automation lane for the frequency of that shelf
* To automate that with my faderport2 I connected the faderport in Jack with QMidiRoute to convert Pitchbend events to Controller events (see screenshot)
* I connected the QMidiRoute MIDI output channel via Jack with Ardour's "MIDI Control in" channel
* Then I CTRL+Middle Mouse clicked the automation fader in Ardour's Edit window
* When the MIDI-learn popup appeared ("operate controller now") I moved the fader of the Faderport
* From there I was able to drive the high shelf of the EQ with the fader and record the automation
* Then I closed the project, shut down the PC
* When reopening the project the next day, without Faderport or QMidiRoute activated, the error message appeared
