I have been unable to get into the QuickBooks file for 3 weeks. After working with QuickBooks, they exhausted every effort on the file and program, and everything is working. They indicated that it is most likely my firewall (Bitdefender) blocking access. This began after the latest Windows 11 update, for which I had to wait for a patch. However, I installed the patch and am still unable to open my QuickBooks. Is there anyone who can help me resolve this issue? At this point, I am desperate. Any advice welcome. Thank you.
