Very long loading times in Windows

We are seeing long loading times in Windows. During the loading there is no GUI visible to let users know loading is underway. This is occurring during initial login, logging into Create, and switching between Create into Classic. The longest load time was switching between Create into Classic. The result of this behavior is that users have no way to know what is going on.

Thank you @WizardATL

We will look into this. If at all possible could you include a screen recording to illustrate this long load time on Windows?

Many Thanks
