External Stylesheet change non-reversible

Hello everyone,

I just wanted to experiment with some external stylesheets for my dashboard created in Python with the Dash library.

My dashboard is structured using the dbc.Row and dbc.Col commands, while I start my code with following line:

app = dash.Dash(external_stylesheets=[‘dbc.themes.BOOTSTRAP’])

This worked perfectly. Today, I changed the external stylesheet to an external URL to, as I said before, experiment a bit, but then realized that it made my dbc.Row and dbc.Col unable to work, which messes up my whole design. I then changed the external stylesheet back to the initial dbc.themes.BOOTSTRAP, but the changes are still there. I am unable to remove the changes I caused using the external URL, I tried reinstalling Dash but it also did not work.

I am quite new to Dash and Python, so I have absolutely no idea how to fix this problem and could not find a solution anyhwere. Any help would be greatly appreciated. Thank you!
