no crashdump created. Win11
Surprisely the save proc itself seems to be successful, but foolowed by crash. Can repro as much as 100%
Today no crash at save, nor on WIN11 
UPD: again… 
and again…
Oh! A hint, that might help: usually after reopening VL - despite of my UAD is selected for audio - I need to “reset audio” to get audio engine work with the UAD.
Heh, narrowed it.
When ignoring to get audio-engine working (see above) at re-launch-VL, then I can work on the project, can save, etc… (of course no AUDIO, but visual tasks to done). Not UAD specific, can crash with GenericAsio with onboard realtek.
Let me know if *.vlproj can help
