Excel White\Blank Screen

Since I am not aware of any official information about a bug, please try the following solution approaches which may resolve your issue.

Based on your scenario (multiple files affected), here's the optimal sequence:

Disable Hardware Graphics Acceleration

How to do it without seeing the screen:

1. Close Excel completely.
2. Open a blank Excel file ( it will be white).
3. Press the Alt key on your keyboard. You should see letters appear over the ribbon tabs (File, Home, Insert, etc.).
4. Press F (for File). 
5. Press T (for Options -  it's usually at the bottom). If you don't see the menu, press Alt again to make the letters appear, then press O.
6. Once the Options window opens (you might have to guess where the "OK" button is or press Enter):

• Press the Tab key repeatedly until you highlight the list on the left.
• Use the Down Arrow key until you hear "Advanced" (or feel for the scrollbar moving). Press Enter.
• Press Tab until you get to the main content area.
• Use the Down Arrow key until you find the section labeled Display.
• Look for the checkbox: "Disable hardware graphics acceleration".
• Press the Spacebar to check it.
• Press Tab until you find the OK button and press Enter.

1. Close Excel and reopen it.

Open in Safe Mode (To check for Add-ins)

If disabling graphics didn't work, a plugin (Add-in) is likely crashing Excel upon launch.

1. Close Excel.
2. Press Windows Key + R on your keyboard.
3. Type exactly: excel /safe
4. Press Enter.
5. If Excel opens normally (with color):

• Go to File > Options > Add-ins.
• At the bottom, where it says "Manage: Excel Add-ins", click Go...
• Uncheck ALL boxes and click OK.
• Restart Excel normally. If it works, turn the add-ins back on one by one to find the bad one.

Printer Driver

Excel tries to format the page based on your default printer. If your default printer is a network printer that is offline, or a "PDF" writer that is broken, Excel renders a white screen.

1. Press Windows Key + R, type control printers, and hit Enter.
2. Find a generic printer like "Microsoft Print to PDF" or "Microsoft XPS Document Writer".
3. Right-click it and select "Set as default printer".
4. Try opening Excel again.

Reset the Excel Registry Key

If the above fails, the internal settings file for Excel is corrupt.

1. Press Windows Key + R, type regedit, and hit Enter.
2. Navigate to this folder path (you can copy/paste this into the address bar at the top of the Registry window):
   Computer\HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Excel
3. Right-click the Excel folder (the one labeled 16.0) and select Rename.
4. Change the name to Excel_OLD.
5. Close Registry Editor and restart Excel.

• Note: This will reset your personal Excel settings (like recent files list), but it often fixes the white screen instantly.

Check "Protected View"

Looking at your screenshot, the filename is PFINK42026.... This looks like a system-generated or downloaded file. If these files are coming from the internet or a network share, Excel might be blocking them in a way that causes a rendering error.

1. Open Excel (even if blank).
2. Press Alt + F then T (File > Options).
3. Go to Trust Center (use arrow keys/tab).
4. Click Trust Center Settings.
5. Go to Protected View.
6. Uncheck all three boxes (Enable Protected View for files originating from the Internet, etc.).
7. Click OK and restart.
