I keep getting CANNOT OPEN MY COMPANY file error

Hi, and thank you in advance.


I use 2019 Quickbooks Enterprise desktop edition and I never had this problem until now.


I installed quickbooks on a new computer. I copied over backups and the main company file. I opened the company file on the new computer, no problems. A few days went by, then one day I tried to open quickbooks and got an error that said my company file could not be opened.  I exited, reloaded quickbooks and tried again. Still got the error, the company file did not load. There was no error code associated with the error.


I rebooted the computer and sometimes I was able to open the company file, and sometimes I was not. When I was not, I reloaded a backup copy. Sometimes the backup would load fine, sometimes It would not open and I get the cannot open company file error.


So I uninstalled quickbooks, rebooted my computer, and reinstalled quickbooks. sometimes the company file would load, sometimes not. 


I am running windows 10, there is plenty of HD space and memory on this laptop.

I tried running the Quickbooks Fix program or whatever it is called and it did not work.

I am running quickbooks on only one computer and not sharing the company file and no multiple users


Of course I cannot keep having this happen, any ideas?  I have run verify, rebuild, etc on the file. sometimes the verify finds a problem and fixes.


I believe I have tried everything. Can't have the company file unreadable at random times and cannot make backups every 30 seconds.


Any help will be awesome!!!
