Additional context In my Windows Server, the Network Service account is the one used for the Azure Pipelines Agent service and I have already given to this user permissions to several folders in C:\Windows\ServiceProfiles... but it keeps throwing that error. On the other hand, my "BuildVariables" in Azure DevOps > Library is empty, since I don't have Azure Key Vault. Is this mandatory or "skippable"? (image attached) Could this be source of the error?

Problem is solved. I reinstalled the agent and recreated the build pipeline.
