Dash-leaflet working in Python 3.9 virtual environment

I am trying to use dash-leaflet within a python 3.9 virtual environment , and the items that I am trying to visualize will not load. In a python 3.7 virtual environment , the visualization does load. However, I need to work within the python 3.9 environment due to other dependencies. When look at google chrome’s console running the code via the python 3.9 environment, I keep getting ReferenceError : regeneratorRuntime is not defined and unstable_runWithPriority errors. Is there anyway for me to fix these errors or avoid them? Any help would be much appreciated!
