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)

I was having this same issue but found a work around which doesn't make a lot of sense. But it worked for me, and now the issue is magically gone. Manually close the shadergraph tab before you run your scene. The error stopped for me. I had it crop up once more when I had it open again, but did the same thing. Now it is not happening at all.
Something strange going on under the hood, which is why some do not have the issue and others do. I was able to keep working though with this option above, hope it helps the rest of you.

Having this issue on URP 2021.1.4, Shadergraph 11.0.0 here. I cannot edit existing shader graphs or create new ones at all. How is this not higher priority, and how come there's no plan to apply the fix before 12.0.0?

Still no conclusion? This problem seems to have no workaround and has entirely halted production on existing SubGraphs. I hope this can be resolved soon.

Sorry, meant to write HDRP 11 on 2021.1.3f1, not 2020.1.3f1.

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.

This also happens on URP for me.
I'm using Shadergraph version 11, and unity version 2021.1.1
