Changes are lost after my modeler got crashed

My modeler (Mendix studio pro version 9.12.5) got crashed and it got switched off automatically and after opening it again, all the changes are lost. I extracted sub microflow from main microflow before my modeler got switched off but now after reopening it, my changes are not in main microflow as well as in sub microflow and somehow, I lost my changes. I can see activities in change-please refer screenshot. Is there any way to get changes back. Note: changes were in my local and not committed.

Hi Rohith, 

Changes will be lost if you haven’t saved your changes.

I hope this helps you
