Step to reproduce:
-1 open FLstudio and add a vital instance in the channel rack
-2 use the transpose snap tool
-3 Close Vital without closing the transpose widget
-4 open your vital instrument again
-5 Crash 100% repro rate
Work around : make sure you don’t have any floating widget opened before you close the pluggin interface.
It’s already been reported several days ago. Updating to FL Studio RC 20.8.0 Build 2098 stopped the crashes but the Transpose Snap window still says open.
It only occurs with the VST 3 version not the VST 2 version. I recommend using the VST 2 version for now.
