Subject: [PATCH] Workaround for .NET6P3 maccatalyst/ios debug on macos (#742)

There was a change in P3 to stop setting this environment variable in maccatalyst and ios which is causing the debugger to hang while connecting on macOS.  This is a temporary fix to bring back the env variable until the issue is addressed.
