Oil line plug/ low oil pressure on cold starts
Oil viscosity at starting and even warm up is much much higher than at full operating termpertures.
When the oil is thick, the pump can push harder, but the additional pressure is not getting more flow to the top.

A 5W-30 will flow better cold, and flow the same at intended operating temps as a 10W-30, especially if its from the same company and product line.
A synthetic will usually flow better cold than the equivalent conventional.
