I just started getting this error in 12.0.1; spent 2 hours downloading the 12.2 beta 3 and I'm still seeing the same issue, even after switching my active developer directory.
Get the "Cannot create Swift scratch context (couldn't create a ClangImporter)" error whenever a breakpoint is triggered, and po/v/p don't return anything. When using the built-in inspector, I get "expression produced no result".
Does anyone have any ideas at all? I'm the only one on my team dealing with this.
