Possibility to skip initial JupyterLab waiting time (workspace clearing)

[alexander-held]

Hi, occasionally (I have not figured out the pattern yet) I get a white screen after the initial loading bar, which can take up to a minute or so. I then get the following message:

The loading screen is taking a long time. Would you like to clear the workspace or keep waiting?

I always click "yes" there, and I do not know what "clearing" actually does in this case (I have not seen anything getting lost in the process). What causes during this loading, and is it maybe possible to configure this to automatically "clear"?
