Resolution Note:
Bug never reproduced in 21.2 as far as I can tell (did not repro in a7 or a6), making this case a duplicate of case 1328377, which was fixed in 2021.1.7f1 (11.0.0)

Yes, cannot even create shaders due to this problem on HDRP 11, 2020.1.3f1. This needs an emergency hot fix please!!!

Any ETA on when this fix will release? It´s impossible to work with SubGraphs at the moment due to this.
This is breaking an essential package marked as "production ready" so I would assume this would have high priority. -

Same happening on Mac Os 10.15.17, Unity 2021.1.1f1 and Shadergraph 11.
I migrated a project from Unity 2020 to 2021 and now my graph are broken when I try to edit them.
