Dash disable button during callback/Dash long_callback bricks my CPU

Dash Python
1

Hi, so basically i want the start-button for a callback to turn disabled during the callback procedure. I have searched a little bit and found the keyword argument “running” (https://dash.plotly.com/reference) for a long_callback which is exactly what i need.
Problem now is that even though i imported the libraries for cache and long_callback_manager like in the examples the programm cant handle it for some reason and my CPU jumps up to a cozy 100%.
Here are some of the relevant code snippets that make my pc unhappy :’)
Import and cache:

from dash.long_callback import DiskcacheLongCallbackManager
import diskcache

print('Programmstart')

cache = diskcache.Cache("./cache")
long_callback_manager = DiskcacheLongCallbackManager(cache)

app = dash.Dash(__name__, external_stylesheets=[dbc.themes.SOLAR], long_callback_manager=long_callback_manager)

The actual callback:

@app.long_callback(
    [
        Output('start_output', 'children'),
        Output('results', 'style'),
        Output('settings_page', 'style'),
        Output('start_button', 'children')
    ],
    [
        Input('start_button', 'n_clicks')
    ],
    [
        State('example_switch', 'value'),
        State('year_dropdown', 'value'),
        State('wind_hours_slider', 'value'),
        State('biomass_switch', 'value'),
        State('biomass_input', 'value'),
        State('solar_switch', 'value'),
        State('solar_input', 'value'),
        State('wind_expansion_switch', 'value'),
        State('planned_wind_switch', 'value'),
        State('methods_wind_check', 'value'),
        State('storage_switch', 'value'),
        State('storage_expansion_switch', 'value'),
        State('storage_expansion_slider', 'value'),
        State('start_capacity_slider', 'value'),
        State('safety_padding_slider', 'value'),
        State('storage_options_check', 'value'),
        State('results', 'style'),
        State('settings_page', 'style')
    ],
    running=[(Output('start_button', 'disabled'), False, True)]
)

If anyone had the same problems or maybe even knows a better solution with a normal callback, please let me know :slight_smile:
