Steps to reproduce:

1. Import the attached package
2. Open New VFX
3. Try to drag and drop ConnectTarget2 to the workspace

Actual results: ConnectTarget2 Subgraph block cannot be released to the workspace and errors are thrown

Expected results: New Output context is created and ConnectTarget Subgraph block is created within that context

Reproducible with versions: 6000.2.0a11, 6000.1.1f1, 6000.0.47f1

Not reproducible with versions: 2022.3

Can’t test with versions: 

Tested on (OS): macOS

Notes:

• Workaround, this block can be still added through node search and or directly dragged to the Output Context{}{}
• It is not reproducible with other Compatible context flags, only Output from by observation
