I've tested one of my AU instruments in progress on Logic Pro 10.7.4, running on OS 13.6.1. When playing a midi file and starting/stopping, it will cause Logic to crash. Anyone else experiencing this?
Just loading instrument and playing it works, it's when starting/stopping a midi-file that it happens.

What is AUVal telling you?

Here's the snippet of the project,

UI script isn't deferred and messing with Messages in the UI script is not a good combination. I would start there.

from the Apple AU Development documentation;

Audio Unit Validation and Testing

Audio Unit Validation with the auval Tool
Apple strongly recommends validating your audio units using the auval command-line 
tool during development. The auval tool (named as a contraction of "audio unit 
validation") comes with OS  X. It performs a comprehensive suite of tests on:

An audio unit’s plug-in API, as defined by its programmatic type
An audio unit’s basic functionality including such things as which audio 
data channel configurations are available, time required to instantiate 
the audio unit, and the ability of the audio unit to render audio
The auval tool tests only an audio unit proper. It does not test 
any of the following:

Audio unit views
Audio unit architecture, in terms of using the recommended model-view-controller 
design pattern for separation of concerns
Correct use of the Audio Unit Event API
Quality of DSP, quality of audio generation, or quality of audio data format 
conversion

The auval tool can validate every type of audio unit defined by Apple. When you run it, 
it outputs a test log and summarizes the results with a “pass” or "fail” indication.

For more information, refer to the auval built-in help system. To see auval help text, 
enter the following command at a prompt in the Terminal application:

auval -h

I realize there's a lot to learn here! Would you suggest putting the messages in scriptprocessors? For instance, these, that now are in onNoteOn callback in the UI script into a scriptprocessor for the sampler that triggers the samples when playing a note?

[d.healey]

@Sampletekk I recommend everyone always adds Synth.deferCallbacks(true); in the on init of their Interface script. It's very rare that you wouldn't want this.

Once you do this HISE will start giving you some errors if you try and do non-deferred stuff in the on note on callback. Anything it complains about you can move to a separate (non-deferred) MIDI processor.

[Sampletekk]

@d-healey So, by putting Synth.deferCallbacks(true); in the onInit interface script you don't need to ad it to other callbacks in interface scripts, that's the only place you should put it?

[d.healey]

@Sampletekk Correct
