After consent to access my bank account, quickbooks goes to a blank screen

Let's run some steps to isolate why the system shows a blank screen, userpdraper101.

There are instances that an issue like this occurs when the system encounters browser-related issues. To start with, let's open QuickBooks on a private window. It is the best place to identify browser-related issues.

You can use these keyboard shortcuts to open one depends on your browser:

• Google Chrome: Ctrl + Shift + N
• Mozilla Firefox: Ctrl + Shift + P
• Microsoft Edge: Ctrl + Shift + P
• Safari: Command + Shift + N

If it works, you can go back to a regular browser and clear its cache. A piled cache can also be the reason for some unexpected issues on the system.

You can also switch to a different supported-browser like  Google Chrome, Mozilla Firefox, Safari, or Microsoft Edge.
