Hi
M. Brian,
As other community member already suggested you to delete the .ldb file may solve your issue.
Reference:
The Microsoft Office Access database engine stopped
the process because you and another user are attempting to change the same data at the same time
other possibility is , if your database is somehow attached with SQL Server database and you left any field empty then Database engine will put lock on that record and you can receive this error.
other thing you had mentioned that, you are not able to open your software.
did you got any error while opening your software? in which project type it was developed?
let us know about that , we will try to provide you further suggestion to solve the issue.
Regards
Deepak
