FYI, when the problem occurred for me all of the QuickBooks files were in the VM's local C: drive and the problem has already been identified as being caused by the November 2025 Windows 11 update which was incompatible with Parallels v21.1 or later. This has nothing to do with shared folders or drive mappings or with Windows permissions to the file location or with the file not being in the local VM C: drive. See https://kb.parallels.com/en/131061Sounds like the recent Parallels 26.1.2 update may have changed how network/file access works in your Windows 11 VM, which can definitely break QuickBooks file loading even though the app itself opens.

It's not uncommon for Parallels updates to tweak filesystem integration and break certain legacy apps.
