I used dash_uploader==0.7.0a1 and it seems to install fine, but when starting the app I get this strange error. Have you encoutered this before? On MacOS (M2 Pro).

Traceback (most recent call last):

This looks the same as https://github.com/fohrloop/dash-uploader/issues/111 - do you think this one can be closed..?

Due to packages version. Installed 21.0 fixed it.
