The error is Windows' "kinder, gentler" way of saying a 0xC0000005 ("C5") error occurred in your app and Windows killed it dead before it could spread i.e. affect other running processes on your computer.

If all the users are getting that message, in some ways it makes it easier to troubleshoot as it must be something common to them all:

- An issue with SQL Server is a possibility. That said, ODBC clients are designed to be fault-tolerant and to not crash hard if there's an issue talking to a SQL server. I've never personally seen a C5 error caused by an issue with an ODBC connection to a remote DBMS

- If everyone loads your app from a server share, a connectivity issue with that server might cause what you're seeing

- If everyone is using the same antivirus app, maybe a bad update is flagging part of your app

- If they have a managed environment, maybe some sort of Windows or other update was rolled out recently to all their computers
