We are configured couple jobs in Visual cron some of them are related to SQL task directly calling the stored procedure from the server by using window authentication, and some of them are related to Backups. Frequently we are getting below mentioned error while executing the jobs.

JobName queued email checker/sender (*****) Job failed at 4/11/2020 5:00 PM with Error:
Msg 18452, Level 14, State 1, Procedure , Line 65536 Login failed. The login is from an untrusted domain and cannot be used with Windows authentication.
Exception in Task: Login failed. The login is from an untrusted domain and cannot be used with Windows authentication..

Please suggest a solution for the above mentioned Issue.

Thank you.

This is almost certainly an Sql Server issue, and not a VisualCron issue. When you says you get this message 'frequently', what does that mean? A login to Sql Server either works or it doesn't. A given login isn't going to work some of the time and fail others. I suspect it happens when some user triggers a VisualCron job manually. You should look in you Sql Server error logs, find the name of the login that fails, and take it from there.
