I am running QB Pro 2020 desktop. I have the latest updates installed as well.
I have been having the same exact issue as talktosomeone. It all started after I attempted to update our logo to a new logo. The new logo is showing properly on the template in the layout format page but when they print, they are cutting off all but the top left third of the logo.
In addition, once I attempted to update the logo, I was no longer able to email. When I attempt to email an invoice, paystubs or any other document, the same problem happens as is happening to coffeelady and talktosomeone, the screen freezes and then says unrecoverable error. I have sent multiple reports to IT regarding this issue and what I am trying to do at the time it happens, so hopefully they are working on this issue.
I found a webpage by Stellar that had several options to try - you can google stellarinfo and qb error 6123 to see their suggestions.
The first two did not work for me but the third option did. I copy and pasted my QB file to another location and then opened it in quickbooks and I was able to email 127 invoices.
However, I have still been dealing with the logo issue and then the emailing stopped working again. I once again moved the file to another location and it would email again. But the logos are still missing. Hopefully, I will get that fixed soon and will not have to keep moving the file location. Not sure if the problems are related but it sure is a coincidence.
