Bot erroring from this week


I have an unattended bot scheduled to run daily. Since Tuesday , my bot is erroring out for some reason or other, yesterday it hit the “time out error” , I increased the time out duration , today it hit with some other error-“Could not find the UI element corresponding to this selector”
If i run the same process manually via the studio , it runs without any error.

Any suggestions?

try using activate activity before the selector.

If you switch between applications in your process, use the Activate in Attach Window / Browser option, as @Mr.StarLord_AO mention.
