Welcome to the Community, @RBQSCKS. I want to help you get past this issue. 

QuickBooks Online uses cache to load the page faster. However, when it becomes full, it behaves poorly or gives you a blank scrreen. 

Let's use a private window to determine a browser-related problem. You can follow these keyboard shortcut keys below:

•  For Chrome, press Ctrl + Shift + N.
• For Microsoft Edge or Firefox, press Ctrl + Shift + P.
• For Safari, hold down Command + Shift + N.

If it works, go back to your main browser and clear its cache and cookies to fix the issue. Once done, restart your browser.

Otherwise, try using other supported browsers like Firefox, Google Chrome, Safari, Microsoft Edge.

Let me know if you need further assistance in resolving the error you've encountered. I’m always glad to help in any way I can. Take care!
