I just inform you that tomorow (01/07/2021) new version of MagicMirror is coming !
I have tested many of my module with it, without any major problem
But, maybe, I think you have to resynch all library with new version of MagicMirror (MMM-Detector/MMM-GoogleAssistant will inform you ! [with no crash or black screen])
You have to use
npm run rebuildin needed module directory
In all case we will be there of offer help is needed !
