2019.3.0b4 assertion failed on expression txn.Exists(guid)

[Fazmo_dev]

this message keeps showing in the editor console window, on a fresh created URP template project.

assertion failed on expression txn.Exists(guid)

assertion failed on expression: ´false´

it doesn’t seem to be harmful, but still a little bit annoying.
