What error is this?

Thanks for taking the time to provide a screenshot of the prompt message you encountered, Nitsu. Let's work together to address this System.AccessViolationException error and get you back on track. 

The error prompt you encountered typically occurs when the program tries to read or write a memory location that it doesn't have permission to access or when there are user permission restrictions. To resolve this and continue working in your Bank Feeds Center, follow these solutions:

Solution 1: Make sure you have appropriate user permissions to C:\ProgramData

1. Find and open your QuickBooks folder in C:\ProgramData. Note that XX stands for your QuickBooks version. Example: Pro 2018 = 18 or Enterprise 19.0 = 19.
   • Pro, Premier, or Accountant: C:\ProgramData\Intuit\QuickBooks 20XX\components\olb\branding\filist\
   • Enterprise: C:\ProgramData\Intuit\QuickBooks Enterprise Solutions XX.0\components\olb\branding\filist\
2. Find and double-click on the fiblueprint.xml file.
3. If the file opens, close it and restart QuickBooks. Retry working on your bank feeds.
4. If you can’t, you need to grant full access to your profile. To do this:

                 a.   Right-click anywhere in the folder and select Properties.

                 b.   Go to the Security tab, then select Edit.

                 c.   In the “Group or user names” section, select Everyone.

                 d.   In the “Permissions for Everyone” section, select Full control.

                 e.   Close the Edit and Properties windows.

                 f.   Restart your computer, then open QuickBooks. Retry working on your bank feeds.
