Is the file in the trashcan?  This is what the stack trace is showing:

7 QuickBooks 2019 0x000000010a3fdb30 FileIsInTheTrash + 114

QuickBooks is supposed to warn you if the file is in the trash but I recall their being a bug in that.  Look in your trash can - if there is a QuickBooks file in there drag it out to your desktop (don't delete it - it may be your most recent file!)  Then launch QuickBooks while holding down the option key. This prevents it from trying to open the last used file.  Then use File->Open menu to navigate to the file.
