😀

I resolved the problem finally:

1) There was a security issue, but also two other issues. There was a syntax error in one of my environment variables in the SSIS catalog that was causing my account to be denied access to one of the database.

2) I had a domain account created and started SQL Server and SQL Server Agent services with this account. I used that account as the job owner. The job still failed. Since my excel file was on another server, instead of using the \\servername\D$\..... I created a share directly to the folder where my files reside and used the sare name. That fixed the problem accessing the Excel file.

Both issues were fixed and the job is now running successfully.
