Application could not be opened - "Start Process" activity

Hi I am trying to run a database using the start process activity and this works most of the time. However, sometimes I will get this error message - “Application could not be opened”
Do you know why this may be?

Can you show us the complete logs (copy to clipboard or open logs)? There can be many reasons for this, the logs should give you a stack trace.

What does “run a database” mean?

Why are you using Start Process instead of Use Browser/Application?
