Setup: Visual Studio Pro 2019 16.8.4, SSIS installed. When I try to access Script Editor Window and update C# code, it does nothing. Never opens nor does it give me an error, it is unresponsive. - Someone else reported this to Microsoft, but there is no real answer yet (https://developercommunity.visualstudio.com/content/problem/1308953/unable-to-repair-visual-studio-tools-for-applicati.html)
I have tried running vsta_setup.exe from Control Panel, but when it tries to repair I get a warning message that it can not locate the latest vsta_setup.exe in C:\ drive. Microsoft's latest vsta_setup file is actually not compatible with VS 2019 16.8.4.
I've tried repairing VS 2019 from installer and I still can not open Script Task Editor when working with SSIS Packages. I'm puzzled why the latest VS Pro 2019 version doesn't have the necessary repair tools to help troubleshoot and fix this issue.
