Hi @Emerald,
Thank you for your inputs. The forum post was helpful. But I have also noticed that this happens when a For each loop is absent in the workflow. Both the origin and the error message is cryptic.
In my opinion, I do have to say to people wanting to port to windows, do not do it, yet. Let the porting / migration tool mature for one more release. This release 20.10.3 is a hard sell. Things will be fixed, but as of now Windows projects has lost us many developer hours in multiple projects.
Our pipelines are also down and we have to manually upload nugets to our different orchestrator enviornments. Again, windows project is the cause. Bug → Packing of Windows version projects → AzureDevops - Feedback / Other Products - UiPath Community Forum
The robots do not have any issues, but Studio as a development interface for windows projects is not mature enough for enterprises.
