I don’t yet know why the build in the plugin manager is not working. I did post my own windows build that seems ok. It’s here: https://github.com/squinkylabs/SquinkyVCV/releases/tag/v1.0.14
So, delete your squinkylabs-plug1 folder and you will stop crashing. Then you can either [temporarily] do without Squinky Labs plugins, or you can download the release, above.
Very sorry for the inconvenience.
