Ableton : deleting a Mellotron instrument crashes

[albanfra]

Not the first time I notice this problem.
When unloading A VSTi, it crashed Ableton Live.
It happened with Solina too.

Live 10.1.9
OSX 10.15.4
Arturia Up to date

Clean install no problem with a lot of other plugs...

Same here, just about everything in the V collection but analog lab crashes when I delete it.
