After applying 4.7 March 2018 CU FP32
K2 Studio crashes silently with an unhandled exception. It only happens when you edit a workflow which uses a custom assembly
Apply K2 4.7 March 2018 Cumulative Update Fix Pack 35 or newer or use the following workaround when you cannot apply a newer FP:
Copy the file SourceCode.Security.Web.dll from directory "[InstallDir]\Host Server\Bin\SourceCode.Security.Web.dll' into directory "[InstallDir]\K2Studio\".
