Same happen to me today, I tried deploying package in SQL Server and setup the schedule but when I executed this error below came:

There was an exception while loading Script Task from XML: System.Exception: The Script Task "ST_36ae893a14204fac97ce8ce3b4ce8ebb" uses version 16.0 script that is not supported in this release of Integration Services. To run the package, use the Script Task to create a new VSTA script. In most cases, scripts are converted automatically to use a supported version, when you open a SQL Server Integration Services package in %SQL_PRODUCT_SHORT_NAME% Integration Services.

Can someone already fix this issue?
