I am encountering a similar issue while using QuickBooks Desktop Pro 2022 on a Windows 11 operating system. I am in urgent need of resolving the problem where QuickBooks fails to back up my company file, displaying an error message stating "QuickBooks was unable to back up your company file. QuickBooks could not copy the company file." I attempted to fix the issue by performing a complete rebuild and verify process, but regrettably, I am still unable to generate a backup file.
