Activites not working when executed with schedule in orchestrator

We have scheduled some processes in orchestrator.
When those jobs run through scheduler in orchestrator some activities like type into gets faulted. Then at the same time after killing this job when we run the same job manually through orchestrator it gets executed.
Kindly help us to find out the issue we have tried giving Send Windows message and simulate click also . But we are still facing the issue.

@Tanvi_Sharma Before Type into activities give some delay and check.

Thanks @indra
I have given both delay before and delay after. Sometimes it works and sometimes it gets faulted.

I am getting same issue @Tanvi_Sharma did you find any solution?please help
