No. There is currently no crossplay between Console and PC, nor between PlayStation and Xbox.

This is not accurate. There is no crossplay between PC and the PlayStation Console. The crossplay in the launcher allows Steam players to play with players who bought the game on GoG/Microsoft Store. These people are still playing on PC.
